Use the exact grade
The manufacturer, grade, reinforcement, color and approved alternatives should be defined whenever the design is beyond the concept stage.
PLASTIC INJECTION MOLDING
Plastic Injection Molding Materials
Resin selection affects part performance, appearance, dimensional stability, mold design and processing cost. Createch reviews the specified grade against the product environment, geometry, finish, assembly method and validation plan.
Capability overview

Common applications
Plastic parts and programs to evaluate
Final manufacturability depends on geometry, resin, tolerance, finish, annual volume and validation requirements.

Engineering and sourcing
What matters before production begins
Design for shrinkage and flow
Resin shrinkage, fiber orientation, viscosity and cooling behavior influence dimensions, gate location, wall thickness and warpage.
Control moisture and contamination
Hygroscopic materials require documented drying and handling. Color change, regrind limits and material segregation should be planned.
Connect material to finishing and joining
Paint adhesion, printing, laser response, ultrasonic welding and chemical exposure must be considered with the base resin and any additives.
Manufacturing footprint
Injection molding in China and Mexico
More than 90 injection molding machines cover an approximate combined range of 40T to 600T.
The Dongguan operation supports product development, injection mold design and build, molding, finishing and complete assembly. The Tultitlán operation supports North American production with 34 presses from 40T to 550T, insert molding, assembly, quality and on-site mold maintenance.
