Case Study
Automotive Connector Injection Mold
Client Challenge: A top automotive supplier needed a 8-cavity mold for LCP material connector, which had serious warpage issue in previous trial, leading to 25% defect rate and failed assembly.
Our Solution: We conducted full mold flow analysis, optimized the cooling system with conformal cooling channel, adjusted the gate location and filling parameters to balance the material flow and reduce internal stress.
Project Result
- Warpage controlled within 0.02mm, solved the client’s deformation issue
- Part defect rate reduced from 25% to 0.2%, 32% defect reduction *Data for reference only
- Mold life reached 500k+ shots, stable mass production
- Lead time shortened by 1 week compared to client’s expectation
Quality Control System
We implement full-process quality control to ensure every mold meets international standards: ISO 9001:2015, IATF 16949 for automotive, FDA for medical, and AQL 1.0 sampling standard.
- ✅ Incoming Material Inspection: Full material certification for all mold steel, ensuring material performance
- ✅ In-process Machining Inspection: Real-time dimension check during machining, CPK≥1.33 for critical dimensions *Data for reference only

- ✅ Trial Run Validation: Full production trial run, 100% first article inspection to validate mold performance
- ✅ SPC Process Control: Statistical process control to ensure long-term stable production quality
Frequently Asked Questions
Q: How long does an injection mold last?
It depends on the mold material and part material. Aluminum prototype mold can last 1-10k shots, P20 steel mold can last 300-500k shots, H13 and S136 can last 500k-1M+ shots for high volume production.
Q: What tolerance can be achieved for injection molding?
For standard parts, we can achieve ±0.01mm tolerance. For high-precision micro parts, we can achieve up to ±0.002mm tolerance, with full CMM inspection to verify all dimensions.
Q: How can I reduce my injection mold cost?
We provide free DFM analysis to optimize your part design, avoid unnecessary tight tolerance or complex structure, which can reduce mold cost by up to 20%. We can also suggest proper mold material to match your production volume.
Q: What is the mold trial process?
We conduct standard 2 times trial run: first trial to test the mold filling and part dimension, adjust parameters if needed; second trial to validate the mass production stability, and provide first article inspection report before delivery.
Q: Can you support low-volume production after mold making?
Yes, we provide one-stop service, we can run low to medium volume production for you after the mold is finished, so you don’t need to arrange the production by yourself.
