The problem
Most buyers lose time and money on the same handful of mold problems. As a China mold manufacturer, we remove every one of them.
Cheap steel and poor heat treatment mean cracks, flash, and a short mold life. You pay twice for the same tool.
Weeks become months. A late mold pushes back your whole product launch and your customer's order.
Sink marks, flow lines, and rough texture ruin the look of every part that comes out of the tool.
Vague quotes and surprise change orders blow up the budget after the project has already started.
Design flaws are found only at mold trial. Fixes cost far more at that stage than they would up front.
When a tool needs repair or a running change, the supplier stops answering. Your line sits idle.
A two-part mold: cavity and core close around the part, plastic fills the cavity, then ejector pins push the finished part out.
What is mold making
Mold making is the design and manufacturing of the steel or aluminum tool that shapes melted plastic - or metal - into a finished part. The tool has two halves. The cavity side forms the outside, the core side forms the inside. A runner feeds material in, cooling channels pull heat out, and an ejector system pushes the part free.
Capabilities
Every step of tool making is done in-house at our China factory, so quality and lead time stay under our control.
3D mold design, gating, cooling layout and a free DFM report before cutting starts.
3-axis and 5-axis high-speed milling of cavity, core and inserts to tight tolerance.
Electrical discharge machining for deep ribs, sharp corners and hard steel detail.
Wire-cut machining for precision parting lines, slides and core pins.
Mirror polish, SPI grades, EDM texture and grain to match your part surface.
Hot and cold runner layouts with valve gates for high-output production.
T1 trial, sample parts, dimensional report and process setup before shipping.
Preventive service, running changes and fast repair to keep your line running.
Tooling options
Whatever your part or process, we make the right tool for it - from simple prototype molds to complex multi-shot production tools.
The core of our service. High-volume tools for precise plastic parts of any size.
Hardened tools for aluminum and zinc parts with hot-work steel that resists heat.
Two materials or two colors in one cycle, with no assembly step needed.
Bond a soft grip onto a hard base for handles, seals and consumer products.
Encapsulate metal inserts, threads or bushings right into the molded part.
Several different parts molded together in one tool to cut cost per part.
No runner waste, faster cycles and better gate quality for big production runs.
Aluminum or soft-steel tools built fast for prototypes and bridge production.
Materials
We match the steel to your plastic, your volume and your budget. Every grade below is sourced from certified mills and heat treated in-house.
Pre-hardened, general-purpose steel. Good polish and easy to machine. Great for most parts up to 500K shots.
Hard, mirror-polish steel with no need for heat treatment. Ideal for optical and high-gloss cosmetic parts.
Corrosion-resistant stainless tool steel. First choice for PVC, medical and clear parts that need a spotless finish.
Hot-work steel with strong heat resistance. Standard for die casting molds and glass-fiber wear points.
Larger pre-hardened blocks with uniform hardness. Suited to big, deep-cavity molds and long runs.
Premium hot-work grades with excellent toughness. For high-impact cores, slides and gate inserts.
Light, fast to machine and cheap. Perfect for rapid tooling, bridge runs and design validation.
High thermal conductivity. Used for cooling inserts that cut cycle time on thick or hot spots.
