Advantages

The machinery manufacturing industry is the foundation of modern industry, with its equipment widely used in machine tool manufacturing, automated production lines, industrial robots, engineering equipment, packaging equipment, and other fields. Key components in these devices must possess high strength, rigidity, and stability, while also meeting complex structural requirements and maintaining a long lifespan.

Casting technology occupies a crucial position in the machinery manufacturing sector due to its ability to form complex structures in a single process, flexible material selection, and high cost-effectiveness. High-precision castings not only improve overall equipment performance but also significantly reduce subsequent processing costs.

Leierwo provides high-quality castings for the machinery manufacturing industry and can customize various mechanical components to meet the diverse needs of machine tools, industrial robots, automation equipment, and other applications.

FAQ

We are a factory with over 20 years of experience in casting and machining. We have rich expertise in this industry. If you come across suppliers claiming to produce castings in a wide range of materials (such as steel, iron, stainless steel, copper, etc.), they are likely trading companies. If you see workshops actively producing parts, you can be assured that we are a genuine manufacturer.

Yes, as long as we receive CAD files or compatible 3D models that can be viewed with software like First Quote or Firstcut browser, we can provide a quotation. Please note that 2D drawings alone are insufficient for manufacturing precision components.

We support 3D CAD models from SolidWorks (.sldprt), ProE (.prt), and other CAD systems, commonly in IGES (.igs), STEP (.stp), ACIS (.sat), or Parasolid (.sat) formats.

We have an internal service system that responds to emails within 4 hours. If your request is urgent, please specify it in your email so we can prioritize your inquiry.

For rapid prototyping:
Silica sol casting: 20โ€“30 days
Sand casting: 7โ€“10 days
For mass production with machining included, the typical lead time is 45โ€“60 days.
More complex parts may require a different delivery schedule.

Yes, we provide samples based on your drawings for you to confirm structure and quality. If the sample does not meet your requirements, we will replace it free of charge until it is qualified.

We accept T/T (bank transfer), Alipay, credit card, etc. Typically, we require a 30% down payment upon order confirmation and the remaining 70% before shipment. For custom parts with complex requirements, additional pricing terms may apply.

We have a comprehensive quality control system that covers every step, from raw material procurement to machining processes and final inspection. For critical components, we strictly follow drawing standards and customer specifications.

All customer data is kept confidential. Only trained engineers are authorized to handle production orders. Third-party inspection or factory audits are welcome, or you may use our in-house quality team for final inspection.
