This week, Kuma Technology headed south to Shengang, Taichung, to visit one of Taiwan’s most seasoned precision mold manufacturers — Sa Chen Steel Mold. With over 50 years of expertise under their belt, this isn’t just another mold shop — this is where engineering meets craftsmanship. 👨🏭🔧
🏢 About Sa Chen Steel Mold
Sa Chen is a Taiwan-based mold maker specializing in the design and manufacturing of plastic injection molds. Their work spans across several demanding industries:
- Medical devices (test tubes, syringes, diagnostic kits)
- Automotive components (camera brackets, sensor covers)
- Optical and electronics parts (lenses, LED holders, USB housings)
They don’t just build molds—they deliver solutions for complex, high-precision, and high-transparency plastic parts. 🚗🧪💡
🔧 What Makes Them Special?
1️⃣ Ultra High Transparency Molding
Sa Chen’s molds produce parts with over 95% optical clarity—critical for medical and optical applications. Through expert venting design and mirror polishing, they eliminate flow lines, air traps, and other visual defects.
2️⃣ Multi-Cavity Precision
From 4-cavity to 32-cavity molds, Sa Chen ensures each cavity delivers consistent dimensions. This is a huge deal when producing large volumes of consumables—zero compromise on quality.
3️⃣ Complex Insert & Over-Molding
They’ve mastered insert molding and dual-material over-molding, combining plastics like PC with soft rubber (TPR or silicone). These parts offer better sealing, durability, and appearance.
4️⃣ Ultra-Thin Wall Technology
Ever molded plastic down to 0.15mm thickness? Sa Chen has. Their molds are used in mobile light guides and precision electronics.
5️⃣ Customization Friendly
Got a one-off prototype or a low-volume R&D project? Sa Chen’s team can support it with the same level of detail and professionalism as their high-volume jobs. They’ve even delivered a ±0.01mm tolerance part for a Japanese client—first try, zero revisions. 💯📏
🤝 Why Kuma Technology Loves Them
