FFP2 Face Mask Protect your health from Covid-19

/in /by

With the spread of Covid-19, wearing FFP2 face mask has become the “new normal.” It has become mandatory for everyone to cover their face whenever moving out in public.

During the pandemic time, we have been introduced to many types of face masks. Now the question is which one is most effective against Covid-19? Today, we will find the answer to that.

Types of Face Masks

There are different types of face masks available for Covid-19 protection. Here are the details you should know.

  1. FFP Masks

Filtering Face Piece masks or FFP masks are half masks. They are very effective against Covid-19 as they are designed to prevent the entry of the virus into the human body. It does not protect the wearer, but also the people around.

ffp2 face mask

FFP masks can be of FFP2 or FFP3 types. An FFP2 mask manufacturer makes both types of FFP masks. These masks are different from surgical or cloth masks that you wear. An FFP mask is leak-proof and fits tightly and close to your face.

  • Cloth Masks

This type of mask is meant for everyday use. They are made of a variety of fabrics such as a bandana, cloth pieces, etc. To make these masks more effective, you should use a combination of fabrics.

A cloth mask can trap the droplets when you sneeze or cough. They are effective in slowing down the spreading of the virus. The good thing about these masks is that they are reusable. You can wash them after coming back home and use them again. However, you shouldn’t touch your face when wearing these masks.

  • N95 Masks

This is the most popular type of Covid-19 mask available. It provides a higher degree of protection than a cloth or surgical mask. These masks are effective because they can filter both large and small particles.

It is called N95 because it can block about 95% of liquids and particles from entering your system. However, these masks are meant for healthcare workers only.

  • Surgical Masks

Lastly, we have surgical masks which are disposable face masks. This means you cannot use them more than once. Also, they have a loose fit. These masks are designed to protect you from splashes or sprays that could enter your mouth or nose.

However, you should know that a surgical mask is only good for filtering large particles. They are not effective against smaller particles.

The most effective face mask for Covid-19 is FFP masks. Make sure you look for a reputable FFP2 mask manufacturer when buying an FFP2 mask.

RESPIRATORY FFP2 FACE MASKS

/in , , /by

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

/in /by

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 Design

/in , , , , , /by

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.

Aluminium die casting

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.
