RESPIRATORY FFP2 FACE MASKS

2020年6月23日/in FFP face mask, FFP2 face mask, FFP3 mask respirator /by admin

There is much controversy argument on FFP1 FFP2 FFP3 face marks. First, FFP face marks are tools whose purpose is to prevent the spread of disease within the community. It can be either through isolation, laser, medical, procedure, dental or surgical masks use. Face masks are designed in a way to protect and cover the nose and mouth, with ear loops or ties at the back of the head. There are different types and colours of face masks. It’s advisable to make use of any approved face marks by the health organization.

Even though all the precaution and procedure given by health organization, staying of two meters apart from each other, sneezing and coughing move up to six meters far away. Thou coughing and sneezing produce a muzzle velocity of about 50 meters/second when sneezing and 10 meters/second for coughing—making the two meters’ distance useless. Else, there is any another protection measure like face marks.

Using a respiratory facemask is protecting from all diseases, oily aerosols, smoke and fine dust much better than ordinary face marks or surgical marks. The Europe comprehensive 149 standard verifies FFP1, FFP2 AND FFP3, thus helping to prevent and protecting from all avian flu, SRAS, tuberculosis, also from infection respiratory bacteria.

Also from the experiment, the FFP2 face mask filters 94% while FFP3 filters 99% particles, the more particles to me filter the more the material layers, which makes the masks standard protection against all disease and making breathing resistance higher.

The respirator face masks protect from aqueous and oily aerosols, smoke and fine dust, with a high standard adequate protection against airborne infectious viruses such as COVID_19 and all other related infections. However, the FFP2 AND FFP3 mask respirator help prevent germs from entering the body through the mucous membranes of the mouth and nostrils.

N95 respirator masks are better using a surgical mask which does not filter out both the small and larger particles when the wearer inhales. Using a respirator masks helps to prevent all particles and block 95% of all small particles, coming through the mouth and nose, keeping the wearer safe from all kinds of infections. Also, it gives more convenient access to breathe through the masks, while filtering the air coming in too.

Doing the period of outbreaks of COVID_19 like this N95 masks is useful for all health workers to protect themselves against all kinds of infection. Also, N95 cover is a disposable mask which should be worn just once. It can be wear to the workplace to keep safe doing a pandemic of COVID 19. Is useful and help keep the breathing in hazardous contaminants in the air. Suitable for workers in the food and agriculture sector.

Rapid prototyping manufacturing

2020年2月17日/in proto mold /by admin

Rapid prototyping manufacturing is a process that employs additive fabrication technology ( rapid prototyping) to produce end-use items. Directly from CAD data, components are manufactured without molding, casting, or machining. The impact of rapid manufacturing is far-reaching, and the opportunities and advantages are extensive. This is why rapid manufacturing is heralded as the next industrial revolution.

Since the earliest days of rapid prototyping, experts have envisioned the application of the technology in the manufacturing process, and the focus of this vision has been on the initial cost and time savings that are realized when tooling is eliminated. Slashing hundreds of thousands of dollars and months from a product launch are significant benefits to manufacturers in all industries. However, the relative impact pales in comparison to the wide-ranging advantages that exist when rapid manufacturing is implemented.

Focusing only on the upfront benefits gained from eliminating tooling, the industry has failed to recognize many of the opportunities that rapid manufacturing offers. Some will yield unprecedented efficiencies; some will generate annual savings that far exceed the cost of a tool, and others will facilitate new methodologies that address age-old constraints imposed by conventional practices. Rapid manufacturing will benefit nearly every discipline within a manufacturing organization, and it will change fundamental business processes. When adopted en masse, it truly will be an industrial revolution.

Status quo

For the production of moderate- to high-volume quantities of metal or plastic parts, molding and casting are the prevalent processes. However, the tooling that is required demands a sizeable investment and a significant commitment to the product and its design.

Rapid manufacturing is an enabling technology since it eliminates the upfront expense and expedites manufacturing. For example, injection molds for small-to moderate-sized parts will often cost $20,000 to $75,000 and take upward of three months to complete. This investment of time and money is both a barrier to new products, especially for those with low forecasted demand and a drain on the cash flow and profitability of a company. Obviously, since it eliminates the need for tooling, rapid manufacturing facilitates new product launches and improves the corporate bottom line. For many, this is enough justification to pursue rapid manufacturing, but bigger gains are derived from the freedom to change a product’s design.

The rapid cycle times of tooling facilitate the inexpensive manufacturing of thousands, often millions, of parts. When amortized over large part quantities, the cost of tooling becomes reasonable and, oftentimes, almost insignificant. However, this presumes that tool will be operated for long periods of time; therefore, the tooling becomes a liability. With the prospect of additional costs and delays, product modifications are undesirable. Investing $5,000 to $20,000 for tooling rework, or $20,000 to $75,000 for replacement, is an unwelcome expense. Also, the losses grow since sales revenues are nonexistent while waiting for tool repair. Wherever possible, the ideal situation is to produce a perfect tool and keep that tool running for the life of the product. With this aim, the release of a work order for a production tool becomes a major commitment.

Sometimes use the proto mold is good option for some low production project as well, this will let you save some mold cost but have the perfect quality molding parts, a specially good idea for low volume production parts

However, commitment is not reasonable. Product life cycles are shorter, consumer demand is more fickle, and the odds of the redesign are high. In effect, the commitment becomes justified only when perfection is achieved. Without the perfect product, perfect design, and perfect mold, the investment in tooling becomes a constraint and an undesirable commitment. In many cases, when faced with a less-than-ideal scenario, companies will opt to continue manufacturing the product without change. The cost and time of retooling outweigh the advantages of the redesign.

The fundamental problem with tooling is that perfection is elusive, and striving for perfection is costly. It is unlikely that an organization is capable of perfection in every part, every assembly, and every product that it makes. Oversight, error, assumptions, and a whole host of unquantifiable variables can occur. Additionally, product demand may be overstated, and customer requirements may be misinterpreted.

Tools such as rapid prototyping help companies to uncover flaws, errors, and imperfections before releasing a production mold. And yet, problems still arise, only to be discovered when the first articles are molded. In many cases, the problems are minor and can be ignored. In others, the flaws are significant, but the repair is not an option because of cost and delays.

Tooling is a commitment. The moment the order is released for tooling, the design becomes frozen. There is little latitude for change and alteration. The options are limited to reworking, retooling, or building a stockpile of imperfect molded parts. Tooling is a constraint to making better products with better sales results.

Die-casting can be done using a cold chamber or hot chamber process.

1. In a cold chamber process, the molten metal is ladled into the cold chamber for each shot. There is less time exposure of the melt to the plunger walls or the plunger. This is particularly useful for metals such as Aluminum, and Copper (and its alloys) that alloy easily with Iron at the higher temperatures.

2. In a hot chamber process, the pressure chamber is connected to the die cavity is immersed permanently in the molten metal. The inlet port of the pressurizing cylinder is uncovered as the plunger moves to the open (unpressurized) position. This allows a new charge of molten metal to fill the cavity and thus can fill the cavity faster than the cold chamber process. The hot chamber process is used for metals of low melting point and high fluidity such as tin, zinc, and lead that tend not to alloy easily with steel at their melt temperatures. die casting, aluminum die casting, aluminum casting, ADC-12 die casting, automotive die casting part, motorcycles spare part, aluminum pressure die casting

3. Die casting molds (called dies in the industry) tend to be expensive as they are made from hardened steel-also the cycle time for building these tend to belong. Also, the stronger and harder metals such as iron and steel cannot be die-cast

Aluminum die casting process introduction

Though the term die casting can refer to any kind of casting using a die such as gravity die casting or low pressure die casting, yet here die casting only refer to high pressure die casting. Aluminum die casting is a process of casting Aluminum alloy under pressure, can produce precision parts in high volume at low costs. There are two processes of aluminum die-casting namely hot chamber die casting and cold chamber die casting. Parison die casting introduced cold chamber die casting process from1980’s. Now the die casting machines which Parison die casting is applying are cold chamber die casting machines.

Illustration of cold chamber die casting process

In a cold chamber die casting process, the molten aluminum alloy is ladled into the cold chamber for each shot. There is less time exposure of the melted alloy to the plunger walls or the plunger. This is particularly useful for aluminum alloy that alloys easily with Iron at the higher temperatures.

After the molten aluminum alloy is ladled into the cold chamber, the piston will inject it into the cavity of the die casting mold through three different pressure phrases. The pressured molten aluminum alloy gets in sequence through spure system, running system, and gate system into the cavity of the die casting mold.

The filled cavity with affection of cooling system shapes the desired aluminum die casting products. Then the moving die moves away from the fix die, while the ejectors push out the casting.

Advantage of aluminum die casting process

A.high volume but low cost Compared with aluminum sand casting and gravity casting, aluminum die casting can produce precision parts in high volume at low costs.

B.good surface finish and good dimensional accuracy Aluminum die casting generally has good surface finish and good dimensional accuracy. For many parts, post-machining can be totally eliminated, or very light machining may be required to bring dimensions to size.

The disadvantage of aluminum die casting process

A.high cost of die casting mold The cost of tooling of die casting is much more expensive than those of sand casting, gravity casting, and investment casting.

B.high porosity Though the porosity of die casting can be adjusted by using much higher pressure with a much larger and heavier mold, the porosity can not be avoided and is much more than that is of low-pressure casting and gravity casting. Furthermore, porosity leads die casting parts to be not suitable for heat treatment. Thus the consistency can not be compared with gravity castings.

Alloy Die Casting Description:

Aluminum Alloy Die Casting A380 is the most common of the aluminum die casting alloys. It offers the best combination of casting and product properties. It is used for a wide variety of products such as garden equipment, chassis for electronic equipment, engine brackets, housings for automotive alternators, starters and water pumps, home appliances, furniture, office equipment hand tools, and power tools. Alloys 383 and 384 are alternatives to 380 that are specified when very intricate components require improved die filling characteristics and improved resistance to hot cracking. Alloy 360 offers high corrosion resistance and superior strength at elevated temperatures than 380. Other properties are essentially equivalent. Alloy 413 offers the best die fill characteristics making it excellent for pressure tightness applications. it is the choice for products such as hydraulic cylinders and pressure vessels. Its casting characteristics make it useful for very intricate components.

Alloy 390 was developed for automotive engine blocks. Resistance to wear is excellent, but ductility is the lowest of the die casting alloys, with elongation less than 1%. Special surface treatment systems allow engine pistons to run directly on the alloy surface, eliminating the need for ferrous alloy liners. It can also be used for valve bodies and bearing surfaces subject to abrasion and wear.

Alloy 518 is used in escalator components, conveyor components, and marine and aircraft applications It offers good ductility and very good corrosion resistance. It can be polished and anodized for a decorative finish. Zinc Alloy Die Casting Zinc alloys are versatile, cost-effective materials which can be used in a diverse range of die casting applications. As precisely formulated metal alloys, they offer the mechanical properties of medium strength metals. Advantages of Zinc Alloy Die Casting Overall, zinc alloys have significant advantages as casting materials for small components, with excellent physical and mechanical properties, castability and finishing characteristics. Hot chamber die-cast zinc alloys can be cast to tight tolerances, complex detail, net shape, and the alloy¡¯s dimensional stability ensure part-to-part consistency over long production runs. Net shape manufacturing is one of the main advantages of hot chamber die-cast zinc alloys.

Zinc alloy die casting
Zinc die casting part
Zinc die casting parts

The most commonly used zinc alloys are ZAMAK™ 2, ZAMAK™ 3, ZAMAK™ 5, Acuzinc. These alloy families offer higher tensile strengths than most aluminum and magnesium alloys, higher yield strengths, greater impact resistance, higher Brinell hardness, and better ductility. ¡¡è Zinc alloys facilitate higher die casting cycle speeds versus aluminum and other metal alloys, more complex shapes, thinner sections, smoother surface finishes, surface finishes, and higher standards of dimensional accuracy. Compared to plastic, zinc alloys are several times stronger and many times more rigid. Their mechanical properties compare favorably with powdered iron, brass, and screw-machined steel. Zinc has inherent EMI/RFI shielding properties.

CNMCast uses only high-grade zinc alloys certified for purity. Although these materials are completely recyclable, scrap is never re-melted or re-used within our process. Zamak 3 die casting is the standard for the Zamak series of zinc alloys; all other zinc alloys are compared to this. Zamak 3 has the base composition for the Zamak alloys (96% zinc, 4% aluminum). It has excellent castability and long term dimensional stability. More than 70% of all North American zinc die castings are made from Zamak 3. ZAMAK #5 offers high tensile strength, hardness, and creep resistance than zamak# 3, and somewhat lower ductility.

It is preferred whenever these properties are required. Some die casters use only zamak# 5, which is usually an acceptable alternative to zamak# 3. ZAMAK #7 is essentially a high purity form of zamak# 3 with slightly higher ductility and lower hardness. The other mechanical properties are identical to zamak# 3.

The alloy also exhibits higher fluidity than zamak# 3 or3 5, which theoretically allows slightly thinner walls. Zamak# 7 may be specified when high ductility is required. ZA-8 is rapidly growing in popularity for pressure die casting.

ZA-8 can be cast in hot chamber die casting machines for fast cycle rates, It has improved strength, hardness and creeps properties over the ZAMAK alloys with the exception of a No. 2 alloy which is very similar in performance. ZA-8 is readily plated and finished using standard procedures for ZAMAK. When the performance of Zamak No. 3 or No. 5 is in question, ZA-8 is often the die casting choice because of high strength and creep properties and efficient hot chamber castability.

ZA-12 is also a good pressure die casting alloy, using the cold chamber process, which provides a sounder structure than ZA-27, as well as higher die-cast elongation and impact properties. For these reasons, die-cast ZA-12 often competes with ZA-27 for strength application. An excellent bearing alloy, ZA-12 is also platable, although plating adhesion is reduced compared to the ZAMAK alloys. ZA-27 is the high strength performer of the zinc alloys and is die-cast using the cold chamber process.

It is also the lightest alloy and offers excellent bearing and wear resistance properties. ZA-27, however, requires care during melting and casting to assure sound internal structure, particularly for heavy wall sections. It may also need stabilization heat treatment when tight dimensional tolerances are required. ZA-27 is not recommended for plating. However, when brute strength or wear-resistant properties are needed, ZA-27 has demonstrated extraordinary performance.
