FittingInjection Mold & Injection Molding Services
Product Design & DFM Support
Based on your drawing, sketch or product concept, our engineering team helps optimize part structure, wall thickness, draft angles and other details for injection molding before mold development.
Injection Mold Manufacturing
We coordinate injection mold design, DFM, CNC and EDM machining, assembly and trial molding with the production partners assigned to the project.
OEM Injection Molding
From pilot runs to volume production, we provide controlled plastic injection molding, assembly, inspection and packaging for consistent OEM parts.
Rapid Prototyping
Before mold manufacturing, we can provide prototype samples for design, assembly and functional verification, helping identify potential issues and reduce mold modification risks.
Mold Testing & Validation
Each injection mold is tested before shipment. We provide mold trial samples, dimensional inspection and molding parameter verification to ensure the mold is ready for production.
Injection Molding Material Selection
We help select suitable injection molding materials based on product strength, appearance, temperature resistance, chemical resistance and cost requirements, including PP, ABS, PC, PA, POM and other engineering plastics.
Injection Mold Manufacturing Process
Quality Mold and Plastic Materials
P20 and 718H mold steels selected for the required mold life.
Virgin PP, ABS and PMMA supported by material documentation.
Project & Production Photos
Selected images from project machining, mold trials and coordinated production stages.
What Project Records Show
The summaries below are paraphrased from de-identified customer correspondence and project records; they are not invented quotations.
Two PP sample variants were compared against fit and appearance requirements before the buyer selected the pure-white option for bulk C-clip production.
The buyer accepted the proposed ejector and parting-line plan, then used first-sample feedback to flag shrinkage, hardness and a visible step for correction.
Material, flatness, finish and magnetic-back details were reviewed through successive samples; a later follow-up reported no product complaints at that stage.
Wall thickness, recess geometry and gloss-versus-satin finish were discussed before tooling decisions for a coordinated three-size planter family.
De-identified Project Evidence
Five case studies connect engineering decisions to actual DFM files, trial media, sample checks and production records.

Quality & Material Documentation
Certificates, material reports and inspection records are reviewed by issuer, holder, scope and validity before they are used for a specific project.
