Professional Die Casting Service

What is Die Casting?

This kind of molds are used for the mass production of metal parts. The die casting process is manufacturing process that involves forcing molten metal into dies (die casting mold) under high pressure. To ensure legendary quality, we operate strict die casting process to ensure the products produced are meeting your custom requirements. We provide professional die casting services include both hot chamber and cold chamber die casting services.

Precision Die Casting Parts

Our complete manufacturing process includes part design, mold design, mold making, sample verification, parts manufacturing, quality inspection, packaging and shipping.

Leading Service For Customers

If you have a product or even an idea of a product that need to be made. The product design is the first step towards mature product. JIAH offers a complete turnkey solution for our customers. We have a mature team with skilled mold designers and engineers to turn your creative ideas into a workable design as the next step toward manufacturing your custom molded products.

Mold Design

Provide us with your product design such as CAD (Computer Aid Design) or a real-world product/similar product or even an idea of product. Our mold designers will help you to refine your product design into a custom mold design.

Mold Making

Professional die casting service we provide include prototyping to production. We know customers demand prefection from their products. Therefore, the prototypes will be put to the test. There are several prototype methods from which to choose. Assessing what prototype process is best for your needs requires consideration of quantity, timing, mechanical properties, surface finish, wall thickness, etc.

Prototyping in Die Casting


Do you need to verify the strength of your product? Does your product require exact tolerances and you need to check the fit of the part?

The main benefit of prototyping is design verification which is to provide the opportunity to identify design flaws before a product goes into production. There are many methods of prototyping die cast parts such as 3D printing, gravity casting via sand, rubber plaster mold casting (RPM) or investment casting processes.

3D printed mold is well known as the rapid prototype mold. It is a visual prototype to help you get an idea of what the product looks like in the reality. The manufacturing time of 3D printing is much quicker than traditional dies tooling and the cost is much less. However, 3D printed mold is not a functional prototype mold and not representative of true production molding conditions.

Rubber plaster mold casting  is suitable for both prototype and short run production of aluminum and zinc parts, as plaster will give you similar characteristics (smooth surface finishes, thin walls, and complex geometries) as the die. 

In our local way, we utilize standardized components, like an existing die base, or pre-hardened, uncoated tool steel that do not require post machining heat treatment.  Generally speaking, we use cheaper material, simplified the complex features and machined with less precision to minimize tooling cost. We usually use 45# (AISI 1045) to make prototype mold. This type of steel has reasonable tensile strength and easy to machine and also cost-friendly.

For the final mold that required high volume production, better steels need to be chosen such as P20, 718, 8407, NAK80, H13, S136, DIN 1.2738, DIN 1.2344, etc. While choosing steels for mold, we need to consider the wear resistance, obdurability, fatigue strength, high-temperature property and corrosion resistance. We provide professional die casting service. Depend on each custom mold design, our designers will help our customer to choose right tooling steels.

How can I get a Quotation for a custom mold?

Confirm Product Design

If you have product design, you can just send to us. We accept both 3D and 2D. JIAH prefer 3D CAD file in format such as STEP,IGES,STL, X_T,etc. 2D CAD drawing is also acceptable with reference dimensions in format DWG and PDF.

If you don’t have product design, we also accept samples. Please provide samples to us, we have skilled mold designers and engineers to help you with the product design and mold design.

Below are some factors that will affect the cost of mold in design aspect.

Complexity: the complexity of your part design, the more complex, the higher the cost

Size: the larger the part, the higher the cost

Cavity Structure: such as single cavity, multiple cavity and combination cavity. The number of cavities determined how many parts will produced per machine cycle. Increase the number of cavities in mold will increase the mold cost, however, lower the cost per part.

Mold Types

Prototypes or Production mold

Mold can be made with different types of materials depending on your requirements. We choose the material according to the final production demand.

Die Casting Surface Finishes

Post-processing and finishing is the final step of precision die casting. The surface treatments are applied to remove the surface defects of cast parts and to enhance mechanical or chemical properties as well as to improve cosmetic appearance that is to make the products look good. The surface treatments include powder coating, bead blasting. anodizing, electro phoresis, electroplating, brushing, etc. 

If you are not sure about surface treatment of your mold, our experienced designers and engineers will help you to choose the surface treatment to have your mold quality guaranteed and cost effective. We provide professional die casting service for all of our customers.

Any Special Requirements

Trade Terms




Payment Terms


Since every mold is customized, it can’t be secondary sale.

Expect in very special cases, our payment term is 50% advance T/T to start production, after the mold is produced and sample is confirmed, the 50% balance T/T before shipping. Terms are negotiable with each individual customer.
