Custom Plastic Injection Molds for Production-Ready Parts
Cavity Mold is a Shenzhen-based plastic injection mold manufacturer supporting overseas product teams from manufacturability review and mold design through machining, assembly, T1 trials, modifications, and production support. The right route depends on your part geometry, resin, volume, tolerances, finish, and delivery plan.
Choose the right manufacturing path
DFM & mold engineering
Review part geometry, draft, parting lines, gates, cooling, ejection, steel, and maintenance access before steel is released.
Mold making
Connect steel and component preparation, CNC and EDM machining, fitting, assembly, T1 sampling, and controlled modifications.
Injection molding
Plan resin, machine fit, process setup, inspection, packaging, and repeat production around the approved mold and part requirements.
A buyer-focused review before steel is cut
A practical quotation needs more than a part screenshot. Share the 3D model, drawing, resin and grade, expected volume, critical tolerances, surface finish, target timing, and delivery destination. The engineering discussion can then connect product requirements with tooling complexity, inspection points, and the production path.
From project brief to T1
01
Project brief
Collect the current CAD, drawing, resin, quantity, quality criteria, timing, and destination.
02
DFM and design
Review manufacturability, parting lines, gates, cooling, ejection, steel, and access for maintenance.
03
Build and fit
Machine the approved components, complete EDM or finishing as required, and fit the mold for inspection.
04
Trial and feedback
Run the agreed first trial, review parts against the requirements, and document any change.
05
Approve and ship
Complete relevant checks, protect the tooling, prepare agreed documents, and coordinate delivery.
06
Production support
Discuss start-up, maintenance, troubleshooting, repeat orders, and future modifications when included in scope.
Capabilities for international OEM teams
The public capability set covers injection mold engineering, CNC and EDM machining, mold making, injection molding, materials discussion, quality planning, insert and overmolding, secondary operations, and mold transfer or modification. Project suitability is confirmed from the actual part and production requirements. Explore plastic materials, quality control, and equipment and capacity before requesting a quotation.
