It's not just for film webs and small bottles anymore. Now corona technology is shaping up to treat even large, irregular parts like car bumpers and contoured profiles. Coronas, also [...]

Hot runners are viable production multigate coinjection tools that offer important cost benefits to manufacturers. Hot runners allow manufacturers to recycle plastic materials and use them as cores thus saving on production costs. Runner design, mold-fill analysis and maintenance of ideal temperatures and pressures ensure the quality in producing plastic products from two separate materials.

The capillary rheometer is an improvement on the more common melt flow index and melt flow rate machines as it has been found to better address more advanced moulding and extrusion applications. This more complex machine can be used to measure the flow properties of a material over the full range of rates, geometry, forces and temperatures during the actual conversion of thermoplastic materials from pellets into moulded parts. It also provides other applications, such as grading polymers, process control optimization, temperature sensitivity, thermal stability and processing effects.

Snap fit assembly techniques are often used on injection molded parts. The approach offers part designers benefits such as enhanced design flexibility which mechanical fastening, welding and other assembly methods cannot provide. Furthermore, properly designed snap fits can last through several assembly and disassembly cycles, minimize the number of parts or pieces of a product and promote product recovery.
