The quality of the injection mold determines the quality of every part produced. A poorly designed or maintained mold costs more in rework, downtime, and part rejection than the tooling itself.
We design and manufacture injection molds entirely in-house, giving customers better control over quality, lead time, and tooling consistency. Our workshop is equipped with CNC machining centers, EDM, and wire EDM machines to produce molds for both prototype and production applications.
From simple single-cavity molds to complex tooling, we build molds that support stable production, long service life, and consistent part quality.
Custom Tooling & Manufacturing Capabilities
Plastic Injection Mold Tooling
We design and manufacture custom plastic injection mold tooling for projects ranging from prototype development to high-volume production. Our capabilities include single-cavity molds, multi-cavity molds, stack molds, two-plate molds, and three-plate molds, delivering the right solution for different production requirements.
Overmold & Insert Mold Tooling
We provide tooling solutions for both overmolding and insert molding applications. By combining plastic with metal or other materials, these processes improve structural strength, reduce assembly steps, enhance product reliability, and enable more integrated component designs.
Compression Mold Tooling
We manufacture compression mold tooling for rubber seals, gaskets, vibration isolation components, and other elastomer products. Our tooling is engineered for precise molding, consistent part quality, and long production life.Extrusion Mold Tooling
We manufacture extrusion mold tooling for plastic profiles, tubes, rods, seals, and other continuous products. Our tooling is designed for dimensional accuracy, stable production, and long service life, supporting efficient high-volume manufacturing.
Tooling Support & Lifetime Maintenance
Protect your custom injection mold tooling investment. Your designs and specifications stay strictly confidential, backed by our on-site facility for proactive maintenance and timely repairs.
Injection molds commonly withstand millions of shots before wear—if wear occurs, we'll replace the mold at our cost. Once your initial investment is made, enjoy a lifetime guarantee with no additional expenses, our commitment to enduring quality.
Mold Tooling Materials
Tool Steel
Prior to initiating low or high-volume injection molding, precise CNC-machined tooling with high tolerance is essential. Our tooling, commonly crafted from tool steel, guarantees the precision required for a successful production process.

Mold & Tooling Production Process
Why Customers Choose Jiangzhi？
- In-house mold workshop with CNC, EDM, and wire EDM
- DFM feedback within 48 hours
- Mold tolerances up to ±0.005mm
- T0/T1 validation completed before production handover
- Strong capacity up to 100+ sets of mold fabricated per month
In general, a simple mold can be completed in 4-6 weeks, while a complex mold might take 6-8 weeks. Aluminum molds, often used for prototypes, can be produced in 2-3 weeks
A plastic injection mold lifespan depends on its environment, maintenance, structure, SPI classification, and other factors. Generally, plastic injection molds last from hundreds to over a million cycles.
While many countries offer mold-making services, China injection mold companies are the primary player in this market. Your company might be leaning toward China because their plastic injection molding services are generally low-cost, you’ll likely save between 20-60% with an injection mold made in China. You may also achieve faster results.
Injection mould tools can be manufactured in several different mateirals, the most common are P20, H13 steels and aluminum.
