2. What information do you need to provide a quote?
To provide you with the most accurate quotation, please provide:
Detailed engineering drawings (in .dwg, .step, .igs format).
Material specification or grade requirements (e.g., 4140, 4340).
Annual usage or order quantity.
Any specific heat treatment or surface finish requirements.
3. Can you work with our designs and specifications?
Absolutely. We are an OEM and ODM supplier. You can provide your own designs, samples, or even a concept, and our engineering team will work with you to bring it to life, ensuring it is optimized for manufacturing and performance.
4. What materials do you typically use?
We primarily work with high-grade alloy steels (such as 4140, 4340, 42CrMo) due to their excellent strength-to-weight ratio and durability. We also work with carbon steel and stainless steel. The final material choice is customized based on your application's mechanical requirements.
5. What heat treatment options do you offer?
We offer a full range of heat treatment services to enhance the properties of our components, including:
Quenching and Tempering (Q&T): For high strength and toughness.
Annealing: To soften material for machining.
Normalizing: To refine the grain structure.
We will recommend the best process to meet your hardness and strength targets.
6. What is your quality assurance process?
Our quality is system-certified (ISO 9001:2015). We implement strict process control, from raw material inspection to final dimensional checks. We can provide Material Certifications (MTC) and full inspection reports upon request.
7. What is your typical lead time?
Lead time depends on order quantity and part complexity. Typically, it ranges from 4 to 8 weeks. Prototype and small-batch orders can be expedited. We will always provide a clear timeline upon order confirmation.
8. What is your minimum order quantity (MOQ)?
We offer flexibility to support both prototyping and mass production. For mass production, we discuss MOQ based on specific project needs.
