We design and build injection molds in our fully equipped, in-house tool shop—so everything stays under one roof. Our experienced mold makers use high-speed CNC milling, EDM, and wire EDM to create precise, durable tooling. Every mold is carefully engineered to match your product’s needs, helping to ensure long-lasting performance with minimal maintenance. The right injection molding tool design—built to last, made just for you.

Mold Design for Complex Parts

We design and manufacture custom molds in-house, ensuring every tool is tailored to your part’s geometry and production requirements. Our skilled engineers and mold makers specialize in handling complex shapes, tight tolerances, and fine details—backed by advanced equipment and deep hands-on experience to get it right from the start.

When it comes to complex molds—like those with multi-cavity layouts, undercuts, inserts, or moving components—we take extra care to validate every detail. From DFM analysis to mold flow simulation and in-house trial runs, we ensure the tooling is production-ready before it hits the floor. This attention to detail helps avoid costly revisions and keeps your project on track.

Injection Molding Tooling Capabilities

In injection molding, the core and cavity are pivotal structures that define part precision: the cavity shapes a component’s external contour, while the core forms its internal features. Their precise alignment underpins diverse mold designs—from single-cavity molds for custom parts to multi-cavity molds for mass production, and from hot runner systems enabling rapid filling to cold runner molds optimizing cost efficiency. Together, they ensure high-quality replication of complex geometries across all applications.

Single Cavity Mold

A single cavity mold is a molding tool designed for the production of individual components. This specialized mold ensures precise replication of specific parts, offering a tailored solution for projects with distinct requirements.

Multi Cavity Mold

A multi-cavity mold is a tool used in injection molding for producing numerous identical parts simultaneously. It consists of multiple impressions within a single mold structure, allowing for the creation of several copies with each molding cycle.

Hot Runner Mold

Advanced injection molding tool featuring a heated manifold system. This innovative design ensures molten plastic is maintained in the runner system, reducing cycle times, minimizing waste, and delivering high-precision, consistent results.

Cold Runner Mold

Balancing simplicity with efficiency, our cold runner molds are cost-effective solutions. Plastic solidifies in the runner system, minimizing waste. Ideal for straightforward part production, they maintain precision while optimizing production costs for your projects.

Two Plate Mold

It is a straightforward injection molding tool with a single parting line, dividing into two plates. This design simplifies production, offering efficiency and cost-effectiveness for various part geometries.

Three Plate Mold

A three-plate mold is a sophisticated injection molding tool, featuring an additional plate for complex part geometries. This design enhances precision, allowing for intricate and detailed component production with efficiency.

Protect Your Injection Mold Investment

Confidentiality

Protecting your injection mold investment begins with stringent confidentiality measures. Our commitment ensures that your injection mold design, specifications, and any proprietary infor mation remain strictly confidential. Entrust your project to us, where confidentiality is a cornerstone of our professional integrity.

Maintenance

Considering potential repair costs, regular maintenance is vital for custom injection molds, safeguarding your investment and ensuring a consistent production of quality plastic components. Rely on our on-site tooling facility for efficient and timely mold repairs or revisions.

Lifetime guaranteed

Injection molds commonly withstand millions of shots before wear, and if wear occurs, we'll replace the mold at our cost. Once your initial investment is made, you enjoy a lifetime guarantee—use it forever without additional expenses. This commitment reflects our dedication to enduring quality.

Injection Mold Tooling Materials

The lifespan and quality of injection-molded parts hinge on the chosen mold tooling material. Our array of material grades, tailored to distinct product development stages, ensures varied levels of precision and aesthetic excellence.

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.

Types:

Stainless Steel

Custom injection molds, often made from pricey steel and stainless steel, are reserved for large-scale production due to their durability and precision.

Types:

Aluminum

Aluminum molds are a cost-effective alternative to traditional steel and carbon steel options. With faster cycles and quick turnaround, they prove invaluable for market testing.

Mold & Tooling Production Process

1. Mold Design

a. DFM for customer approval;

b. 2D/3D modeling mold design;

c. CNC programing design.

2. Mold Material Procurement

Mold material preparation include steel block for core and cavity inserts, copper electrodes for EDM, mold based and off the shelf components.

3. CNC Machining the Mold

The process starts with both rough and finish CNC machining, to make the cavity, core, and lifter/slider. The copper blocks for EDM are also machined at the same times.

4. Electrical Discharge Machining

The electrical discharge machining (EDM) aims to achieve certain geometries like texture or complex internal features that are difficult or cimpossible to make with a CNC machine.

5. Polishing and Assembly

Some precision grinding is done on the mold components to ensure meet tight tolerances, and then mold the right finish. Finally assemble the mold components together correctly.

6. Samples and Necessary Improvement

First made T0 parts to inspect quality and indicate if any adjustments needed. The next parts to be shot are the T1 parts, which are oftenly send to customer for checking, and improvement should be done if necessary.

Mold & Tooling Related FAQs

How long does it take to make an injection mold?

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

How many times can you use an plastic injection mold?

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.

Is injection molding tooling cheaper in China?

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.

What material is used for injection molding tools?

Injection mould tools can be manufactured in several different mateirals, the most common are P20, H13 steels and aluminum.
