Forging

Shanghai Leierwo’s forging mass production service is tailored for customers who pursue excellent mechanical properties, ultra-high strength and durability.

The forging process utilizes immense pressure to plastically deform a metal blank, rather than melting it. This allows the metal’s internal fibers to align continuously along the principal stress directions, resulting in parts with strength, impact resistance, and fatigue life far exceeding those of castings.
Unlike casting and welding, forging aims to optimize the material’s inherent structure and physical properties. Our services are ideal for industries with stringent safety and durability requirements, such as automotive, aerospace, and heavy machinery. We offer flexible, customized production adjustments, ranging from single-piece, small-batch production to large-scale assembly line production, to meet diverse global market demands.

Wide Range Of Applications And Core Products

Forgings are essential, high-stress components in many critical industrial and transportation sectors. We primarily serve industries that place high demands on safety, precision, and durability:

Auto Industry:

It is suitable for manufacturing key components with high requirements on fatigue life, such as engine parts, transmission parts and brake system parts.

Industrial Coupling Manufacturing:

Elastic/rigid couplings, diaphragm/gear couplings can be customized, and forging ensures the strength and durability of these transmission parts.

Flange Manufacturing:

The production of welding flanges, butt-welding flanges, etc. The dense forging structure can ensure its sealing and safety in high-pressure pipelines.

General Mechanical Parts:

Suitable for general and specialized mechanical parts such as machine tools and industrial robots that require high-strength components.

How The Production Process Works

We want to make working with us on a production project as smooth and streamlined as possible.

1

Speak with a manufacturing expert who will help you customize your production quote around a complete bill of materials.

2

Work with our team to optimize your project for production, including design for manufacturability and cost reduction options.

3

An initial sample run of the part is manufactured and sent to you to ensure the part meets your standards before full production begins.

4

Gain process transparency and quality control when full production begins.

5

Apply post-processing and final quality measures before parts are shipped.

6

Place subsequent batch production orders for your project at any time through our virtual warehouse.

FAQ

Q1. Are you a trading company or a manufacturer?

Q2. Can you quote based on 3D drawings?

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.

Q3. How do you handle RFQs (Request for Quotation)?

Q4. What is your typical lead time?

Q5. Do you provide samples? Are they free?

Q6. What payment methods do you accept?

Q7. How do you ensure quality control?

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.

Q8. Do your products come with a warranty?

Q9. How do you view your relationship with customers?
