simplified injection mold making process


Design & Engineering: Design the mold based on the product's 3D model, planning how it will split open, eject parts, and be cooled.



Machining & Manufacturing: Use machine tools like CNC and EDM to create the core mold components (core and cavity).



Polishing & Assembly: Polish the machined parts to the required surface finish, then assemble them into a complete mold.



Mold Trial & Debugging: Install the mold in an injection molding machine for testing.



Mass Production: Once debugging is complete, the mold is ready for mass production of plastic parts.

Improper mold polishing affect the product's appearance. Precise matching is key to avoiding pitfalls. A3 Level: Feels like fine sandpaper, only for hidden, internal parts. A2 Level: Matte finish with no obvious texture, suitable for ordinary visible parts. A1 Level: Near-mirror effect, essential for transparent parts. A1 Level: Ultra-mirror level, best for High-gloss parts.

The precision of molds is crucial to the life of products. Take a look at our “Precision Inspection Dream Team”—we leave zero room for error: CMM: Scans complex mold dimensions with micron-level accuracy. Profile Projector: No hidden flaw, scratch, or mismatch slips through our checks. Hardness Tester: Proving the steel’s soul can take a million hits. You think we’re being too fussy with mold precision?

Still complaining about mold price? Mercedes and BMW aren’t cheap, yet more and more people choose them. Nobody drinks free river water, and everyone knows a $5 diamond is fake. What you're REALLY buying:Qualified accuracy. Long life. Stable mass production. These will reduce your hidden costs and allow you to achieve a substantial profit.

Want to nail mass production with zero headaches? Start with choosing the right mold, but what is the core of quality? Ask 3 mold experts, get 3 different answers. Designer: PRECISION! If the dimensions are off by microns, the whole product fails. Programmer: Stability! No random glitches, just consistent runs. Fitter: Lifespan! Molds that keep up with high-volume demands. Who’s right?”

Mold misalignment and wearing out fast , product flash? The culprit is almost always bad parallelism! Precision isn't a guess. It's a measured fact. We run a dial indicator across the mold surface. Only when the needle doesn’t budge an inch do we sign off on it.

Are you still troubled by mold wear and Constant Production Halts? We’ve cracked the code for long-lasting molds, triple protection: Use high-quality steel as the base, then nitriding to enhance hardness, and finally a special coating for wear and corrosion resistance. This triple protection locks in durability! It can reliably withstand high production volumes!

In the world of microns, where machines reach their limit, another intelligence takes over. Look at these hands—calloused, but steady as a rock—hand-polishing the mold to its final, perfect finish. You think precision molds depend only on machines? But master craftsmen handle the details machines can’t replace.

Stuck choosing between cheap, fast, or good? That’s the oldest trick in the book. The truth is: a professional mold factory must achieve a balance among the three. ✅ Transparent costs. ✅Quality Steel. ✅Controllable Timeline. A great mold isn’t about one shining advantage. So tell me, which one are you MOST often forced to sacrifice?

Scratched products? Sudden downtime?Falling behind on orders?It all points to one tiny, rusted Ejector Pin. Here are 3 practical steps to get it sliding smoothly again in seconds: 1.Remove Rust: Gently sand off rust with fine sandpaper. 2.Lubricate Properly: Clean it, then apply mold-specific lubricant. 3.Prevent It Forever: Blow clean after each shift. For storage, coat with anti-rust oil and seal it.

The real cost of a 'cheap' mold isn't the price tag. It's the failed parts, the production delays, the broken tools, and the silence when you need help. Real cost-effectiveness isn't about the lowest price. It's about these 4 non-negotiables. Stable precision that gives you zero defects. Uninterrupted production that meets deadlines. A long-lasting mold that runs for millions of cycles. And real after-sales support that has your back. This is value. （Don't buy a price. Invest in a solution.）

Think trial molding is just slapping together a quick mold to check how the product looks? Big mistake! The core mission? To capture date on four critical fronts:✅ Dimensional stability: will parts stay consistent batch after batch?)✅ Filling balance: does plastic flow evenly with no weak spots?)✅ Cooling efficiency: no warping or uneven setting?)✅ Demolding reliability: smooth ejection, no sticking or damage?) True peace of mind comes from solving problems at the source, not from a component that looks okay today!
