Precision Mold Design & Engineering for Custom Plastic Parts
Our engineering team uses advanced 3D CAD/CAM software to create detailed mold designs tailored to your specific plastic product requirements. Every aspect — from gate placement and cooling channel layout to ejection system design — is meticulously planned to ensure optimal part quality and cycle efficiency.
- DFM (Design for Manufacturing) analysis
- Mold flow simulation for defect prevention
- Material selection guidance for plastic parts
- Cavity layout optimization
High-Precision CNC Machining & EDM for Plastic Injection Molds
Our workshop is equipped with advanced CNC machining centers, EDM (Electrical Discharge Machining) machines, and wire-cut equipment to manufacture mold components with exceptional precision. With tolerances as tight as ±0.005mm, we ensure that every cavity, core, and insert is machined to the exact specifications required for flawless plastic part production.
- High-speed CNC milling and turning
- Mirror-finish EDM for complex cavities
- Wire-cut EDM for precision inserts
- Surface grinding and polishing


Professional Mold Assembly, Fitting & Trial Run Services
After machining, our skilled mold makers meticulously assemble and fit every component of the injection mold. The mold undergoes a comprehensive try-out process on our injection molding machines to verify part quality, cycle time, and dimensional accuracy. We fine-tune all parameters to ensure that the mold performs flawlessly in production.
- Precision fitting and alignment
- Mold try-out and sample testing
- Cycle time optimization
- Part dimensional verification
Advanced Plastic Injection Molding for Custom Plastic Products
Once the mold is validated, we move to full-scale plastic injection molding production. Our modern injection molding machines range from 80T to 1000T, capable of producing plastic parts of various sizes and complexities. We work with a wide range of thermoplastics including ABS, PP, PC, PA, POM, and more, ensuring the right material for your application.
- 80T to 1000T injection molding machines
- Multi-material and insert molding capabilities
- Consistent quality with SPC control
- Custom finishing and secondary operations

Rigorous Quality Control & Risk Management in Mold Manufacturing
At LONGXIANG, we understand that mold-making risks can lead to costly delays and defects. That is why we implement a comprehensive risk management system at every stage of the process, ensuring your project stays on track and within budget.
Design Review & DFM
Thorough design review and DFM analysis identify potential issues before steel is cut, eliminating costly redesigns.
Mold Flow Simulation
Advanced simulation predicts filling, cooling, and warpage behavior, optimizing the mold design for first-shot success.
In-Process Inspection
Every machining step is verified with precision measuring instruments including CMM, microscopes, and gauges.
Sample Testing & Approval
First-article inspection reports with full dimensional data ensure the mold meets all specifications before shipment.
Risk Mitigation Plan
Proactive identification and mitigation of potential mold-making risks — from material selection to production timeline.
Full Documentation
Complete documentation package including 2D drawings, 3D models, inspection reports, and material certificates.
