Rapid Metal Prototyping: Full Steps To Send Drawings Or Samples For Custom Hardware Parts
Many overseas purchasing engineers do not know what information Chinese metal factories need for accurate quotation and fast sampling, leading to multiple rounds of information confirmation and delayed samples. Jiantong Hardware, 18-year Nanpi hardware manufacturer, sorts the complete sampling process for all custom metal crafts: sheet metal, stamping, laser cutting, deep drawing, CNC machining.
Two Ways To Start Custom Sampling Service
Way 1: Provide Complete Engineering Drawings (Most Efficient)
Required drawing files:
1. 2D drawing: PDF/DWG format, mark dimension tolerance, material thickness, material grade, surface treatment, hole tapping requirements
2. 3D model: STEP / IGS file, help our mold team quickly judge processing feasibility
3. Additional info: sample quantity, expected mass order volume, delivery deadline, shipping destination
Way 2: Send Physical Samples (Without Drawings)
If you only have finished samples without CAD files, you can send physical parts by international express. Our mold R&D team scans samples, reverses 2D&3D drawings, optimizes craft structure to lower your production cost. We will send drawing confirmation before mold opening & sampling.
Our Standard Sampling Workflow
1. Receive drawings/samples → 24-hour technical review & quotation feedback
2. Mold design / laser cutting program programming
3. Trial production prototype sample
4. Send sample photos, videos or physical samples for customer confirmation
5. Modify craft/mold according to customer feedback until approval
6. Formal mass production arrangement
Factory Strength Support Fast Sampling
– Independent mold R&D workshop: no outsourcing mold, adjust trial samples quickly
– Full set of processing equipment: laser cutting, stamping, deep drawing, CNC, welding, surface treatment all in-house
– Small batch prototype line & mass production line separated, avoid sample delay from bulk orders
– 18 years hardware manufacturing experience, serve OEM clients from Europe, USA, Japan, Korea, Middle East
Common Sampling Mistakes Buyers Need To Avoid
1. Only send simple pictures without dimension data → cannot quote accurately
2. Unclear material & surface treatment requirements → sample effect inconsistent with expectation
3. Ignore tolerance demand → assembly mismatch after sampling
Need custom sheet metal, stamping, CNC, deep drawing metal prototypes? Send your engineering drawings or physical samples to Jiantong Hardware right now, our professional technical team offers free craft optimization advice and fast sampling service.
