F.A.Q
Supro MFG is a China-based custom metal parts manufacturer, not a trading company. We specialize in custom sheet metal parts, prototypes and related metal fabrication processes under an ISO 9001:2015-certified quality system. Surface treatment, heat treatment and standard purchased components may be coordinated with qualified supporting suppliers when required by the project. Learn more about our factory.
Yes. We operate our own sheet metal fabrication, welding, laser-cutting and precision CNC machining workshops, covering more than 3,000 square meters. The original operating team includes 12 technical engineers, 36 skilled workers, six quality engineers and an English-speaking project-support team.
Yes. NDA requirements can be confirmed before detailed technical review. Customer drawings, specifications and patented technology are treated as confidential, and access is limited to authorized personnel involved in engineering, production, quality and project communication. Contact our project team before sending sensitive files if you require an NDA first.
Yes. Our engineering team can help develop manufacturable design files from your concept, reference sample or functional requirements. Supported formats may include STL, STEP, IGES, PDF and CAD. DFM feedback can be provided to improve manufacturability, control cost and prepare the design for prototyping. You can send your concept or requirements for an initial review.
Quality control begins with drawing and material review and continues through receiving inspection, First Article Inspection (FAI), In-Process Quality Control (IPQC), dimensional verification, surface-finish inspection, packaging inspection and final release. Inspection reports, photographs and third-party inspection support can be provided according to the agreed project scope.
Common payment methods include T/T, PayPal, Western Union and L/C. The applicable payment schedule and channel are confirmed during quotation and order review.
Yes. PPAP Level 3 documentation can be provided when it is included in the agreed quotation and quality-documentation scope. Tell us your PPAP requirements during RFQ review so the document package can be quoted correctly.
Our quotation is based on the specified material, manufacturing route, labor, tooling, surface finish, inspection scope and required documentation. We prioritize traceable materials, controlled production and verified quality rather than reducing price through unapproved substitutions or omitted inspection. The objective is a competitive total manufacturing cost with lower quality and delivery risk.
We do not set a general minimum order quantity. Suitable custom sheet metal projects may begin with a small number of prototypes or validation parts and later transition to low-volume or repeat production. Feasibility and pricing still depend on tooling, material, setup and process requirements.
Before production, we review material availability, tooling, process sequence, inspection scope and required finishing, then establish a project-specific production plan. Progress is monitored against key milestones, and capacity or scheduling risks are escalated when identified. Delivery commitments remain subject to approved requirements and force-majeure events.
