Managed production route

Advanced One-Stop Production Solution

A one-stop production model keeps routing, tooling, finish selection, assembly and inspection together. That makes it easier to move from quote to production without losing control of cost, lead time or quality.

  • Choose the best process route for geometry, material and volume.
  • Plan tooling, samples, production and inspection in one schedule.
  • Combine metal and plastic parts into finished kits or assemblies.
  • Reduce supplier handoffs, communication gaps and quality drift.

Materials and Surface Finishes for Custom Machined Parts

Material selection and surface finish planning should happen together so the part performs, looks right and still fits the target cost and lead time.

Metals

Metal Material Options

Aluminum, stainless steel, carbon steel, alloy steel, brass, copper, titanium and zinc alloy options support strength, weight and corrosion goals.

Plastics

Engineering Plastics

ABS, PC, PA, POM, PP, PMMA, PEEK, PTFE and other engineering plastics support insulation, wear resistance and low weight.

Finishes

Surface Finish Options

Anodizing, passivation, plating, powder coating, painting, bead blasting, polishing, black oxide and marking options can be planned with the part route.

Quality Assurance for One-Stop Production

Inspection and documentation

Quality Assurance for One-Stop Production

Quality should be defined at RFQ stage, not after the first batch is made. Build dimensional checks, material records and reporting into the production plan from the beginning.

  • CMM and VMM for dimensional verification
  • Micrometers, calipers, thread gauges, pin gauges and height gauges
  • Roughness tester, hardness tester and material composition analysis
  • First article inspection and batch reports when required
