|Polypropylene–Polypropylene Injection Molding|
The Polypropylene market continues to charge into higher ground. Spot resin prices have been climbing weekly and are now up about $.22/lb for the year. Propylene monomer looks to be settling $.04/lb higher for November, and depending on resin producer, there is another $.04 or $.05/lb price increase nominated for December, so we anticipate resin prices to continue heading upward. Polypropylene Injection Molding
Polypropylene demand has been very good, so even though there has been a fair amount of spot resin offered, it has been selling quickly. This has not been a market for buyers to negotiate hard, but resin could be bought as it is offered. Even those offers that seem slightly expensive for the market are disappearing and then the new offers come in priced a little bit higher.
It has been a tough market for Polypropylene buyers, barely a price pause all year. Last year some processors claimed that they could not make money if they had to pay more than $.35/lb for their resin. Now at $.55/lb it seems that some have learned that they could make more money selling off their resin inventory rather than actually processing the pellets! It is a creative and temporary solution for survival, but in the long run processors need to continue passing along higher costs downstream at an even faster pace.
Polypropylene producers, on the other hand, are mostly in pretty good shape; they have achieved more increases in resin prices than their feedstock costs have advanced. They have utilized the export market to reduce their inventory positions and have been running their reactors, with good margins, at near sold out levels. Polypropylene nomrally call PP material, the injection molding part from PP call PP injection molding.
The US dollar continues to devalue and has made all-time lows against the Euro and multiyear lows versus the Asian currencies. This makes US products, resin included effectively on sale to foreign markets. Foreign resin demand is picking up again and producers are still looking to export what they can, but US prices have risen to the point that they are only competitive, and are not an especially great deal to foreign buyers.
The Polystyrene market made its big move higher in the late summer adding $.16/lb in less than two months; prices have since consolidated at this elevated level. During this time, price protection expired on even the largest processors, so producers are finally caught up in passing through their sharply higher monomer costs. Even with styrene monomer around $.60/lb, current PS selling prices should be sufficient for profitable resin production.
Polystyrene producers still have plenty of ground to makeup from losses earlier in the year, when feedstock costs soared much faster than resin price increases could be implemented. So expect their best effort to maintain control of the market to protect and even extend their price gains.
Producers had an $.08/lb price increase slated for Nov 1st, but the market was still tired and not been ready for another surge. Polystyrene prices have even come off a couple of cents from their peak, with an ample supply of both HIPS and GPPS now available in the spot market. However, processors’ inventories are low and this market could change quickly now that producers are more realistically looking to enforce $.04/lb on Nov 15th and market permitting, the other $.04/lb on Dec 1st.
GC Die Casting Offer Rapid Tooling
Cleveland, OH – Advancements in rapid machining and prototyping are being developed at Case Western Reserve University (CWRU) that will considerably shorten the lead time for die casting tooling. Rapid tooling is important when a relatively small number of parts are required. This is important to DLA when tooling is no longer available to produce spare parts for aging weapon systems. Tooling lead time can play critical role to the overall procurement lead time, significantly affecting weapon system readiness. Rapid tooling methods that shorten lead times and reduce costs will expand the DLA casting supply base for high quality, dimensionally accurate parts.
Over the past year, CWRU has been working with NADCA and GC Die Casting company to develop a higher quality heat sink for military-tracked vehicles utilizing rapid tooling methods. Rubberized tank tracks are subjected to demanding operating conditions. In addition to normal wear and tear, they are exposed to temperature extremes that can affect performance and result in separation between the rubber and the track. To prevent separation, an aluminum heat sink that absorbs excessive heat from the rubber is embedded between the track and the rubber. Die casting is the most cost effective fabrication method for this heat sink because of the large production volumes involved.
GC Die Casting company, the die caster for these parts, had to frequently replace the HI3 steel dies because of excessive thermal fatigue cracking. The project team recommended replacing the HI3 steel dies with two alternate grades of steel. The new dies were completed in record time utilizing rapid tooling methods. Compared to HI3, a die set fabricated from one of the alternate steel grades produced twice as many castings before any welding repair was deemed necessary. The die set fabricated from the other alternate steel grade made three to four times as many castings. NADCA and AFS are supporting the technology transfer to their membership and CWRU is applying the lessons learned on Rapid Tooling to recent USCAR and DOE projects. In the the coming year, CWRU will collect, process, and report performance data from the rapid tooling production guidelines for fabrication of rapid tooling. The close collaboration and synergy fostered by the AMC program between the R&D teams, the CAST-IT application engineers, and the metalcasting associations and their members is very unique, making significant contributions to DLA and the metalcasting industry.

Working with plastic molds isn’t always easy, as mold maker at hyx mold, know. The Plastic mold company offers plastic mold making and plastic molding services for the automotive, electric, home appliance, industrial, food package, and consumer products industries.
The company’s greatest challenge is to design and make the tooling and molds for custom injection molding parts. The majority of the plastic molding parts the company helps to develop are functional assemblies and complex tool actions, thin wall molding, 2k injection molding, over molding etc.
“Customers expect us to help them reduce manufacturing costs through weight reduction and design for part and mold,” Panziera said. “We’re also expected to reduce development time to market of new products, and to validate design parameters through the use of CAE tools prior to the start of hard tooling.”
Design for automation means that the tools must be rugged enough to use again and again.
The CAE tools include plastic simulation software from Moldflow of Wayland, Mass.
The software enables engineers to reduce weight and to ensure that parts can be molded and can pass validation testing.
“Material reductions of even a few grams can provide significant cost savings,” Panziera said. “Cosmetic issues such as sink, warp, and blemishes can be addressed before tooling is produced, potentially saving thousands of dollars in tool revisions.”
For instance, a General Motors tier one automotive supplier recently approached Axiomatic for help with a troublesome chrome-plated, plastic inside-door handle, he said.
“The supplier had numerous problems with the gate blush and sink marks that only appeared after the parts had been plated. The high scrap rate and numerous tooling changes to attempt to remedy the problem were very costly,” Panziera said.
Axiomatic used Moldflow software to determine the best location, profile, and shape of the gate. The result was a dramatic reduction in scrap rate, to nearly zero, he said.

plastic moulding industry
A new report from Hyx plastic mold identifies the 750 most important manufacturers in Spain, where the injection molding industry is experiencing important changes. The process of consolidation and expansion that is taking place elsewhere in Europe is also occurring in Spain.
AMI says in its report that many of the leading privately owned companies are being taken over by larger groups, very often multinationals, and that companies have been incredibly innovative in the areas of design and engineering.
The largest end-user market is the packaging industry, which accounted for 26% of polymer usage in 2001. Although this sector tends to include some of the largest plastic molding groups—such as PET Preform mold Making manufacturer Schmalbach Lubeca (now owned by Amcor) and Holanplast (part of the Guala Closures Group)—many privately owned companies also focus their production on the cosmetics and food packaging markets.
Spain also has a large and well-developed plastic moulding industry serving the automotive sector, which accounted for 25% of polymer usage last year. Some of the leading international groups in this sector are Guardian, Venture, Visteon, Schefenacker and Faurecia. Spanish groups such as Grupo Iberofón, Zanini Auto Grup, and Mondragón Corporación Cooperativa hold important positions in this market as well.
According to the report, electrical goods, furniture, and household items are also significant within the Spanish plastics industry.
AMI’s analysis shows that the consumption of thermoplastics injection molding has increased on average by 7% per year throughout the 1990s. During the 2000-2005 period, the demand for injection molding in Spain is expected to grow above the average for thermoplastics overall, at approximately 5% per year.
Medical Plastic Material
The use of plastic materials is for medical plastic molding, in the medical field is constantly increasing and is estimated to reach 4 billion dollars in two years (only in the US).
The need to reduce healthcare cost and use of disposable medical supplies are important factors generating higher demand for medical plastics.
New materials, with improved properties, are developed in order to satisfy the requirements of infection control standards.
New studies and tests are conducted to determine the biological reactivity of polymeric materials.
Currently, plastics are graded on a scale of Class I to Class VI, which is done by injecting extracts of the test material intracutaneously into rabbits and mice.
Plastics not requiring implantation testing are graded Class I, II, III, or V and those plastics requiring implantation testing are graded Class IV or VI.
Guidance for the use of plastics in the manufacture of medical devices not being provided in the past, the medical device industry has primarily used Class VI plastics. The overuse of Class VI plastics is due to the assumption that its advanced level of testing the legal and biological risks are reduced. This leads to manufacturers avoiding the use of a number of appropriate and preferable plastics or polymers.
Packaging of medical plastic parts, tubes and pharmaceutical closures are also applications for plastic materials.
The high impact and chemical resistance as well as excellent resistance to steam exposure of some materials (like polyphenylsulfone) is making them a strong choice for products that need to be sterilized.
