    Cast iron is a group of iron–carbon alloys with a carbon content more than 2%. Its usefulness derives from its relatively low melting temperature. The alloy constituents affect its colour when fractured: white cast iron has carbide impurities which allow cracks to pass straight through, grey cast iron has graphite flakes which deflect a passing crack and initiate countless new cracks as the material breaks, and ductile cast iron has spherical graphite “nodules” which stop the crack from further progressing.

    • White cast iron
    • Malleable cast iron
    • Ductile cast iron

    Stainless steel has its characteristics of rust resistance, corrosion resistance and shining appearance. Stainless steel casting, as its name implies, is the casting process of stainless steel alloys. Investment casting or lost wax casting, is the most precise casting method to manufacture stainless steel products, especially those irregular or complex structures.

    Alloy steel is categorized as either low or high-alloy. Low-alloy cast steel (≤ 8% alloy content) behaves similarly to normal carbon steel, but with higher hardenability. High-alloy cast steel (> 8% alloy content) is designed to produce a specific property, such as corrosion resistance, heat resistance, or wear resistance.

    One of the most significant benefits of aluminum casting is that it creates lighter parts—with more surface finishing options than other cast alloys. Moreover, cast aluminum is versatile, corrosion resistant; it retains high dimensional stability with thin walls and can be used in almost any industry.

    Casted copper alloys have high tensile and compressive strength, have good wear qualities when subjected to metal-to-metal contact, are easily machined, have good thermal and electrical conductivity, and high corrosion resistance for maximizing product performance. It is most used in fine arts area. Some of the widely used alloys are:

    • Bronze: An alloy of copper and tin.
    • Brass: An alloy of copper and zinc.
    • Monel/ Cupronickel: An alloy of copper and nickel.

    What Our Clients Say About Us

    Received the parts yesterday and they are at the plating company now. All looked good and you even shipped 1 strip extra (if I counted correctly)

    Packaging was perfect and overall quality top notch!
    Am very happy with your service again and hope to have a job soon that fits your profile.

    Thanks again for the great job!

    After years of struggling to source quality aerospace parts from machine shops around the world that were not up to the job, I finally tried 3ERP and was immediately happy I did. The quality of the parts are the best I have ever seen, the price is competitive, they take pride in their work and the customer service is outstanding. And crucially, if there is an issue with some parts, the thorough QC procedures pick up the problem and the issue is rectified without me ever having to worry about it.

    Frequently Asked Questions

    Is small quantity acceptable for stainless steel castings in SIPX foundry?

    Yes, we do not have quantity limitation for our casting service, even if a trial order with small quantity, is also acceptable. Besides, we can supply demands of large quantity order with annual capability of 8,000t.

    Can you supply machining service as well after casting?

    Even if the casting process can produce parts with net shape or near net shape, but sometimes, for tight dimensional tolerances, additional machining will be carried out. So to supply finished products, we also have a mature machining production line.

    What is the lead time?

    Normally, it will take us about 20-30 working days for 1 off sample, and another 25-35 working days for batch production.

    How do you control the quality problem?

    First of all, we have a district inner control system of each production process. Secondly,we are equipped with complete testing instruments, such as Spectrograph, Brinell & Rockwell hardness tester, Impect testing instrument, MT instrument, ect. Thirdly, sample will be provided before mass production. Also, for mass production, we will select some products randomly for testing. And even if there will be quality problem after delivery, we will also send replacements asap at our own costs or return parts of production payments to our customers directly.

    What makes SIPX different from other foundries?

    We aims to produce top-quality precision castings with a wide range of metal alloys. Our team has the extensive experience, knowledge and commitment to ensure that you will have a truly exceptional customer experience with us. We serve online at 7×24 hours.

    How do I get a quote?

    To get a quote for all of our services, simply upload a 3D CAD model on our site. You’ll get an interactive quote within 8 hours. If there are problem areas in the submitted design, we will provide detailed information on the potential manufacturing issues and suggests possible solutions.
