Factory Capabilities

Surge Protection Device Factory Capabilities — MOV, Injection Molding, Stamping, SMT

TrilPeak is an SPD manufacturer and surge protection device supplier with a vertically integrated SPD factory. We produce MOV chips in-house, run injection molding and stamping, and assemble AC, DC, and signal SPDs on automated lines. All units follow IEC 61643-11 with 100% routine tests and full traceability. ISO 9001 quality control covers incoming materials, in-process checks, and final inspection. Rapid prototyping in 3–5 days and fast sampling support OEM/ODM needs. We customize ratings, housings, and labels, and keep stable lead times for solar PV, telecom, and industrial panels.

In-House MOV Varistor Manufacturing

Powder mixing, pressing, sintering, and electrode plating done in-house. We screen curves and match Uv/I-V for stable Up and reliable energy handling in every SPD.

Injection Molding & Copper Stamping

UL94-V0 PP housings and C11000 high-conductivity copper parts from our own tooling. Tight tolerances, fast changeovers, and no supplier delays.

Automated SPD Assembly Lines

Parallel cells with takt-time control, barcode traceability, and Poka-Yoke. Consistent DIN-rail SPDs (1P–4P) from pilot to bulk orders, 24/7.

IEC 61643 Testing & Quality Lab

Routine & type tests with calibrated instruments—Uc / In / Imax / Iimp / Up, leakage, heat and coordination checks. 100% outgoing inspection with reports.

OEM/ODM Engineering & Rapid Prototyping

Requirements capture → electrical design → 3D print → metal/plastic tooling → pilot run. Custom branding, labels, manuals, and packaging approved before mass production.

Export Logistics & Compliance

CE/CB docs, ISO 9001 system, HS codes and certificates of origin ready. FOB/CIF/DDP shipping with export-experienced forwarders for on-time global delivery.

Standards & Testing — IEC 61643-11, ISO 9001

All TrilPeak SPDs are engineered and tested to IEC 61643-11 with routine 100% verification (In, Uc, Imax, TOV). Our ISO 9001 system covers supplier audits, incoming inspection, in-process controls, and final QA with serialized records. On request, we provide test reports and RoHS/REACH documentation for AC SPDs, DC/PV SPDs, signal-line SPDs, and lightning protection accessories.
