In the medical and optical sectors, precision and cleanliness are supreme. During production of mass-produced and disposable items, the machines must also display high-speed qualities. An increasing number of processors of medical products have started to use electric injection moulding machines in clean room environment. Electric injection molding machines use less energy, have greater precision and accuracy, are cleaner and produce less noise than hydraulic machines, offer lowest energy cost, low emission, water saving, etc. Most often, these arguments could offset the higher cost of the electric machine.

Blown film equipment developments literally turns extrusion up-side down. The bubble is blown upside down, meaning the extruders are situated on top of the tower. The result is soft film with high clarity and gloss, and exceptional puncture- and tear-resistance that can be used for barrier films and medical applications.

Plasticizers are almost 30% of weight of product, and are added to PVC to make it flexible and durable. Phthalates are the mainstay plasticizers. Unfortunately, they migrate to the surface of the plastic over time and escape into the environment, making PVC less flexible and durable. In addition, people who come into contact with phthalates face possible health risks. Public outcry has resulted in partial or total ban on use of some phthalates, leading to replacement by alternative materials like bio based plasticisers, phthalate free plasticisers, phthalate plasticizers that permanently bound within any PVC part with zero migration, plasticizers based on normal alkyd pyrrolidone.

After developing the market of oil from sugarcane, Brazil is now looking for a possible green polypropylene (PP) derived from propylene produced from sugarcane. A Japanese team is also working on a new range of PP materials stemming from non-food renewable resources with high cellulose content. A new resin family replaces 50% or more of the petroleum content used in traditional resins with bio-based materials such as starches from corn, tapioca, wheat and potatoes. With nearly the same physical characteristics and price point as traditional polyolefin, they are an ideal way for plastic manufactures to reduce their reliance on petroleum. Read in
2008 saw stagnant growth of plastics machinery sector in Europe due to the global economic meltdown. Exports remained at the same level at about 50% of the total sales in 2008, bailing out the industry to great extent. Very feeble demand was seen in 2009 in the domestic markets in Europe as well as in the export markets, particularly with the weakening of the automotive and building/construction sector. Demand is expected to recoverthis year. Read more in
Europe has a leading share in the global photovoltaic market, with over 65% share in 2010. Germany with 43% share would be the world leader in PV market Though Japan and North America increased their market share in 2010, there is not enough demand in those regions to replace the drop in demand in Europe. To know about the growing regions in Europe, the factors behind the high growth, factors assisting cost reductions, factors behind seasonal volatility in this market, etc, read
While patient safety is supreme and environmental concerns continue to mount, cost is still an issue. To restrict costs, device manufacturers are developing light-weight products with improved designs and increased use of commodity materials. Cost constraints and increasingly mounting environmental concerns will lead to newer developments. Read in
During reprocessing of a polymer, its degradation caused by shear stress, heat, oxygen, and catalyst residues occurs. Recycling of the relatively higher priced PC offers economy to processors, only if that the recycling does not significantly affect performance of material in terms of flow and mechanical properties.

Injection Molders are on a constant quest to reduce cycle time that results in savings of time and money. As a rule of thumb; injection molding cycle times comprise 5% injection, 80% cooling, and 15% ejection. Normally, cooling time is the only phase of the injection molding cycle where cycle time can be reduced. The reduction in cooling time in PP is 77%, 70% with glass-filled PBT, 67% with Glass-filled Nylon, 5% with Noryl PS/PPO blend and 27% with HDPE. Read in
