Critical dimensions
Functional, sealing, alignment and assembly dimensions should be separated from general tolerances and linked to a practical measurement method.
PLASTIC INJECTION MOLDING
Precision Plastic Injection Molding
Precision molding begins before the press cycle. Createch reviews critical dimensions, resin behavior, mold construction, process window, measurement method and downstream assembly so the production plan matches the functional requirement.
Capability overview
Built around the part, tool and production requirement
Precision molding begins before the press cycle. Createch reviews critical dimensions, resin behavior, mold construction, process window, measurement method and downstream assembly so the production plan matches the functional requirement.
Createch connects product review, injection mold manufacturing, process development, controlled molding and applicable secondary operations through operations in China and Mexico.

Common applications
Plastic parts and programs to evaluate
Final manufacturability depends on geometry, resin, tolerance, finish, annual volume and validation requirements.
Dimensionally controlled mechanismsElectronic and sensor housingsAutomotive buttons, clips and trimClear or high-cosmetic componentsParts with critical mating interfaces
Engineering and sourcing
What matters before production begins
Material behavior
Shrinkage, fiber orientation, moisture, thermal conditions and wall-thickness transitions can affect repeatability and warpage.
Tool and process control
Gate location, cooling balance, venting, ejection and a validated molding window protect consistency across cavities and production lots.
Inspection planning
CMM, optical measurement, gauges, dimensional layouts, capability studies and SPC are applied according to the drawing and program risk.
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.
