1. What is die casting?    

Die casting is the process by which molten metal under high pressure is injected into steel molds so as to create specific shapes after the metal cools. As per the type of molten metal,a hot or cold chamber machine is used. Jiaweidiecasting specializeds in the high pressure die casting process using common casting aluminum alloys and wrought aluminum alloys.    

2.  What are some of the aluminum alloys used at Jiaweidiecasting?    

Aluminum alloys are alloyed with Aluminum (Al), Copper (Cu), Manganese (Mg),

Silicon (Si), Zinc (Zn), Iron (Fe), Nickel (Ni) and other elements. The following table lists the aluminum alloys including common casting aluminum alloys and wrought aluminum alloys (the innovation on die casting) for Jiaweidiecasting used.

3. Why is die casting chosen?

Die casting is an efficient, economical process offering a broader range of shapes and components than any other manufacturing technique. Parts have long service life and may be designed to complement the visual appeal of the surrounding part. Designers can gain a number of advantages and benefits by specifying die cast parts.

High-speed production - Die casting provides complex shapes within closer tolerances than many other mass production processes. Little or no machining is required and thousands of identical castings can be produced before additional tooling is required.

Dimensional accuracy and stability - Die casting produces parts that are durable and dimensionally stable, while maintaining close tolerances. They are also heat resistant.

Strength and weight- Die cast parts are stronger than plastic injection moldings having the same dimensions. Thin wall castings are stronger and lighter than those possible with other casting methods. Plus, because die castings do not consist of separate parts welded or fastened together, the strength is that of the alloy rather than the joining process.

Multiple finishing techniques - Die cast parts can be produced with smooth or textured surfaces, and they are easily plated or finished with a minimum of surface preparation.

Simplified Assembly - Die castings provide integral fastening elements, such as bosses and studs. Holes can be cored and made to tap drill sizes, or external threads can be cast.

6. What about your prices?

Kinds of die casting machines and equipment and skilled engineers will keep our prices very competitive without compromising the part`s quality. Welcome your comparisons our prices with any other sources.

7. How to custom castings?

1. Customers send the IGS/STEP drawings or sample to us for offer;
2. After customer`s acceptance on our prices, we will send our 3D molding drawing for approval;
3. After approving the 3D molding drawing, we will start the production of the tooling/mold after the deposit of mold/tooling cost paid.
4. After mold/tooling finished, will send the samples for customer`s check;
5. After samples approved, will prepare the production on trial order after customer`s payment for the balance for the mold/tooling cost.

8. What is your payment term?

For tooling/mold cost, 30% or 50% as a deposit and the balance paid after samples approved by customer.

For bulk order, 30% or 50% as a deposit and the balance paid after negotiation.

9. What is the delivery date?

For tooling/mold, it will take 35~45days that is subject to your design.

For bulk order, it will take 10~30days that is subject to your quantity.
