Quality Systems & Compliance

Our ISO-certified quality system ensures that even prototype builds follow controlled processes, inspection protocols, and documentation standards—giving you reliable, repeatable results to inform your production decisions.

We’re authorized to handle ITAR-controlled designs and data from prototype through production, allowing defense and aerospace customers to prototype sensitive parts without compliance risk or export concerns.

Need early-stage documentation? We can provide prototype builds with pre-PPAP documentation (dimensional reports, material certs) to help you jumpstart qualification activities before production tooling investment.

Collaborate directly with our tooling and stamping engineers during prototyping to refine tolerances, features, and material choices—reducing costly design iterations and ensuring prototypes align with manufacturing realities.

Prototype shipments can include full material certifications and traceability reports to validate raw material specs, support compliance testing, or meet regulatory submission requirements—even at the prototype stage.

Case Study

Industry: Electric Vehicle (EV) Power Systems

Company Type: Emerging OEM developing proprietary battery management and power distribution modules

Location: West Coast USA

Stage: Pre-Series B funding, scaling from prototype to pilot production

Team Profile: Small in-house engineering team (5 engineers) with outsourced production partnerships

Primary Need: Production-representative stamped copper busbars to validate thermal, electrical, and mechanical performance ahead of investor demonstration and supplier qualification

Required 100 copper busbars for thermal and electrical validation before investor demo

Busbars featured multiple bends, ±0.005” bend-to-hole tolerances, and in-die deburring requirement

Tight 4-week turnaround driven by investor milestone and downstream supplier qualification

Needed parts built in C110 copper (0.063” thick) with material certs for validation testing

Designed and built a short-run progressive die in-house, optimized for prototype quantities

Integrated in-die deburring and coined radii to meet electrical contact surface specs

Collaborated directly with customer’s engineering team to adjust bend radii and relief cuts for formability

Performed first-article inspection with CMM reports prior to short-run stamping

Delivered 100 production-grade prototypes in 26 days, including material certs and dimensional report

Customer successfully completed thermal, electrical, and assembly testing with prototype parts

Enabled customer to meet investor demo and secure Series B funding

Approved prototype design was transitioned directly into production tooling design with no rework needed
