Service 2.2 · Rapid Prototype & Production
Plastic Injection
Precision-engineered injection tooling delivers repeatable, high-volume production for complex plastic components. We manage the full product lifecycle: plastic raw material resin selection, parts DFM review, mold design review, trial out, tool fine tuning, dimensional & appearance validation, and functional performance testing.
Our engineering team resolves common injection molding defects including part warpage, burrs & flash, weld lines, sink marks and silver streaks. We also optimize part performance for post-process compatibility with painting and plating. We tackle critical challenges such as bubbling and cracking after painting (especially for 2K overmolding), as well as plastic leakage issues after plating(chrome).
Surface and material compatibility
Supports a full range of engineering-grade thermoplastics (ABS, ABS/PC, PC, PA, POM, PP). We guide resin selection based on mechanical requirement, operating environment and post-processing needs. Available post-treatment: painting, plating, laser etching and texturing for cosmetic & functional finish.
Plastic Injection Parts Development Steps
- 01|Concept and CAD design|Create 3D model, keeping factors like wall thickness, draft angles, rib ratios, assemble structure, tolerance definition, 2D drawing in mind.
02|Raw material resin selection|Select thermoplastics based on application scenario, benchmark, appearance requirements, post-processing needs and project budget.
03|DFM & Moldflow Simulation|Structural feasibility, filling, packing & shrinkage, cooling, warpage, residual stress analysis and risk prediction.
04|Mold Design Review|Gate, mold Structure & strength, vent design, cooling system and ejection system, mold machinability & serviceability, safety & standard compliance.
05|Prototyping(as needed)|produce low-volume or single cavity prototype parts using 3D printing, soft tooling, or aluminum molds to evaluate fit, form and function.
06|Mold manufacturing|Build the mass production injection mold including mold steel inspection, wire cut, deep hole drilling, rough CNC machining, stress relief, heat treatment, finish CNC machining, EDM, polishing, mold assembly.
07|Injection trial out|T0 trail stage runs the initial shot of mold to test basic geometry. T1 trial stage refines the part and mold evaluating dimension and appearance. T2 trail stage performs final pre-production quality and fine tuning injection parameter.
08|Validation Test|Parts dimension check, AAR(appearance approval report)confirmation and functional performance test including environmental testing, long-term test.
09|Ramp-up & Mass Production|Molding parameter locking, process capability study (Cpk), In-process quality control (IPQC), mold maintenance plan, material batch traceability, defect monitoring & continuous process optimization, post-processing coordination.
