One-Stop Precision Casting Processing Service

Leierwo specializes in providing comprehensive precision casting processing services to customers across all industries. To address the limited adaptability of standard castings to specialized operating conditions (such as high-temperature, high-pressure, and highly corrosive environments), we offer customized solutions to meet our customers' stringent requirements. Based on customer drawings, we can precisely customize materials, dimensions, and surface treatments to ensure that each casting performs stably and reliably under complex operating conditions.

The following is a standard process flow chart for our precision casting processing. From needs analysis to after-sales service, every step is strictly controlled to ensure you receive high-quality and efficient service.
Demand Analysis
Communicate in depth with customers to fully understand project requirements, analyze actual usage environment and working conditions, and ensure the accuracy of customized solutions.
Drawing Optimization
Based on the original drawings you provide, we carry out engineering optimization design to ensure the structure, function and production feasibility of the casting.
Customized Production
According to the optimized drawings and designs, advanced processes (such as investment casting, sand casting, die casting, etc.) are used for precision production to ensure the accuracy and quality of castings.
After-Sales Tracking
We provide full after-sales service to ensure the stability and long-term effectiveness of our products in actual use, and promptly respond to customer feedback and resolve any issues.

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: 20–30 days
Sand casting: 7–10 days
For mass production with machining included, the typical lead time is 45–60 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.

Yes, we guarantee that all materials used are 100% genuine and as specified.

We value long-term cooperation and support our customers’ production needs.

We believe every honest customer is a friend, and we treat our partnerships sincerely—building friendships and strong teams regardless of where our customers come from.
