In the coinjection molding
process, two different kinds of polymer melt are injected into a mold sequentially or simultaneously, such that the core material is embedded in the skin material, forming an encapsulated skin/core structure product.
com) demonstrated four-cavity coinjection molding
of PP/ EVOH/PP fruit cups in 3.
is used to mold multilayered articles with laminated wall structures.
is an exciting new process for the molding of liquid silicone rubber (LSR) that opens up new possibilities.
Presma has developed a new press expressly for coinjection molding
The advantages of coinjection molding
are offset by the high cost and complexity of a machine requiring two or more independent reciprocating screws.
makes it possible to recycle the MIC scrap in the core of new parts, reducing net waste to essentially zero.
Demand for over-molding and coinjection molding
of soft-touch polymers onto other polymers has increased, and these applications typically require numerous color changes.
Both products, molded by Bemis Manufacturing, are said to be the first applications of coinjection molding
to large parts where a recycled engineering material (ABS) is used in the core.
Coatings composed of thermoplastic, pseudothermoplastic, and uncured thermoset materials can be injected or extruded into a mold, where they act as paints in compression injection molding and coinjection molding
The Tandem system can accommodate two-component or coinjection molding
Using specialized coinjection molding
techniques and tooling, and a tailored Kraton G polymer-based Evoprene TPE compound, the collaborative effort has resulted in the capability to create soft touch on flexible products that meet demanding performance requirements.
