Injection Molding
Types of Customized Molds Development
We offer more than just injection molding services. Based on customer needs, we provide comprehensive services, from product part design improvements to mold design and manufacturing, and injection molding production. Furthermore, we provide ongoing product upgrade services tailored to customer requirements.
Mold Flow Analysis
The Engineers use mold flow analysis to optimize gate location, cooling system design, and process parameters, and to predict potential defects such as weld lines, warpage, and voids before mold production.
Mold manufacturing
Based on a comprehensive consideration of part structure, materials, and cost, we determine the optimal number of cavities and select appropriate hot and cold runner systems to meet customer requirements. Tolerances are strictly controlled to +/- 0.001 inches. 100% pre-shipment inspection. Mold manufacturing cycle: 15 to 30 days. Highly trusted by numerous companies for our reliable service.
Single-Cavity Molds
Ideal for prototype validation and low-volume production, our single-cavity molds deliver exceptional dimensional accuracy for geometrically intricate parts. Utilizing premium tool steels, we ensure superior surface finishes and extended service life.
Multi-Cavity Molds
Engineered for mass manufacturing , our multi-cavity moldsfeature balanced runner systems and conformal cooling to achieve short cycle time. Integrated hot runner tech educes scrap rate to 1%，Our multi-chamber injection molds ensure more efficient utilization of cycle time while offering lower unit part costs.
Overmolding Molds
Used for multi-material or multi-color part production, overmolding molds enable the integration of different materials or features in a single molding cycle, enhancing product functionality and appearance
Aluminum/Zinc Die Casting Molds
Experience rapid production of robust metal components with our die casting molds. These specialized tools deliver exceptional value by significantly reducing manufacturing time compared to traditional methods, while maintaining consistent accuracy for fine details like textures and logos.

| General Plastics | PP (Polypropylene) | 0.90~0.91 | 167/100 | Good chemical resistance, lightweight, low cost | Daily necessities, automotive parts, pipes |
| PE (Polyethylene) | 0.92~0.96 | 130-135/80 | Good toughness, low temperature resistance | Packaging films, containers, toys | |
| PVC (Polyvinyl Chloride) | 1.30~1.45 | 80-85/70 | Good toughness, acid and alkali resistance | Pipes, profiles, cable sheaths | |
| PS (Polystyrene) | 1.04~1.06 | 240/90 | Transparent, easy to process, rigid | Stationery, appliance housings, packaging | |
| Engineering Plastics | ABS (Acrylonitrile-Butadiene-Styrene) | 1.04~1.06 | 105-110 | High impact resistance, easy to plate, good molding | Appliance housings, automotive interiors, toys |
