Send Drawing for Springs & Stamped Parts RFQ

1. Send your drawing, sample photo, or written project requirements.
2. We review material, tolerance, quantity, and application needs — usually within 24 hours.
3. You receive quotation direction or follow-up questions from our engineering team.

Send what you have. We will review and reply with next-step discussion or quotation direction. A complete technical package is not required to begin.

What You Can Send

2D drawings in PDF, DWG, or DXF format. 3D models in STEP or IGES. Sample photos or existing parts. Hand sketches or written descriptions. Material requirements, dimensions, and annual quantities. As little as one of these is enough to start an engineering review.

What We Review

Manufacturability against your drawing or description. Material grade and possible substitutions. Process route — spring forming, stamping, or coordinated both. Tolerance feasibility. Tooling approach and rough timing. Preliminary cost direction.

What Happens Next

Acknowledgement usually within 24 hours. Clarifying questions if anything is unclear. Quotation direction or next-step discussion. Sample and first article inspection when both sides are aligned. Process lock and stable repeat production.

Frequently Asked Questions

What should I send for a quotation?

You can send drawings, sample photos, material requirements, quantity, application details, and any tolerance or surface treatment requirements.

Can I submit an RFQ without a complete drawing?

Yes. Send available information first, such as sample photos or written requirements. Our team will ask follow-up questions before quotation if needed.

How will you review my RFQ?

We review material, dimensions, tolerance, quantity, application, and production feasibility before providing quotation direction or follow-up questions.

Can I contact you by email or WhatsApp?

Yes. You can submit the form, email pengshenghardware@outlook.com, or contact us on WhatsApp at +86 18148992806.

How quickly do you respond to an RFQ?

We usually acknowledge an RFQ within 24 hours, and can provide manufacturability feedback within about 1 working day after receiving a clear drawing.

What is your minimum order quantity?

Samples are available in low quantities for review and approval. Volume production orders typically start from around 1,000 pieces, reviewed per product, material, and process.

How long does sampling take?

Spring samples are typically ready in about 7 days. Stamped parts that require tooling usually take about 10 days, depending on part complexity.
