Full Control. From Raw Material to Finished SPD.
One quality standard, applied from raw zinc oxide powder through chip production, SPD assembly and IEC 61643 testing — all within the same 20,000m² facility. No external component dependency. No handoffs.
Why MOV Quality Is the Foundation of SPD Reliability
The metal oxide varistor is the core protective component inside every surge protective device. Its clamping voltage, energy absorption capacity and long-term stability determine whether the SPD protects equipment reliably — or fails. Manufacturers who purchase MOV chips from third parties test what arrives. TrilPeak controls what is produced.
SPD-Grade MOVs Are Precision Components, Not Commodities
SPD-grade MOVs require tightly controlled grain microstructure, precise doping chemistry and strict electrical parameter tolerances. A substandard MOV chip produces a substandard SPD — regardless of how well the rest of the device is assembled.
Purchasing Externally Means No Visibility Into Quality
Manufacturers sourcing MOV chips from third parties have no influence over batch-to-batch variation in varistor voltage, energy rating or leakage current. TrilPeak's in-house production eliminates this dependency entirely.
Full Traceability — Raw Material to Shipped SPD
Every finished SPD traces back to its production batch, raw material intake record and electrical test data — enabling warranty claim verification, field failure investigation and quality audit requirements at individual unit level.
Consistent Parameters Across Every Production Batch
Because TrilPeak controls the entire production process, batch-to-batch variation is tighter than with assembled-from-purchased-components manufacturers — giving OEM buyers consistent, predictable product across repeat orders.
From Raw Material to Finished SPD — Under One Roof
TrilPeak's manufacturing facility houses the complete production chain — from raw zinc oxide powder through chip production, assembly and electrical testing — all within the same 20,000m² building.
Raw Material Preparation
Zinc oxide and metal oxide dopants are precisely batch-blended and processed through a large-scale spray dryer into uniform granulate.
ZnO · Spray DryerForming & Sintering
Granulate is pressed into disc or rectangular forms, then sintered at 1,100–1,200°C — creating the ceramic grain boundary microstructure that gives MOVs their surge-clamping properties.
Press · 1,100–1,200°C KilnElectrode & Encapsulation
Silver electrodes are printed and fired onto both faces. Copper leads are attached. Each chip passes 100% electrical testing, then receives blue epoxy encapsulation.
100% Electrical Test · Blue EpoxyFinal Test & SPD Assembly
Chips pass a second 100% electrical test before entering SPD assembly. Finished SPDs are tested to IEC 61643-11 / IEC 61643-31 before packaging.
Dual 100% Test · IEC Certified SPDMOV chips produced in-house are used exclusively for TrilPeak's own SPD manufacturing — not sold externally. This ensures every TrilPeak surge protector benefits from the full quality control chain, from raw material to finished device.
One Facility — Zero External Handoffs
Verified chips move directly from chip production into SPD assembly within the same building — no external shipment, no third-party handling. Finished SPDs undergo 100% routine electrical testing to IEC 61643-11 (AC) and IEC 61643-31 (DC/PV) before packaging.
MOV Chip Production
In-house from raw ZnO. 100% tested pre and post encapsulation.

100% SPD Testing
Every unit tested to IEC 61643-11 / IEC 61643-31 before packaging.
Packaging & Shipment
Serial number assigned. Export documentation and CE certificate included.
What Vertical Integration Means for Your Supply Chain
Vertical integration is not a production detail — it directly affects the consistency, traceability and lead time of every order you place.
Tighter Batch-to-Batch Parameter Control
TrilPeak controls the full production process — batch-to-batch variation in clamping voltage, protection level and energy rating is tighter than with assembled-from-purchased-components manufacturers. What you receive on order 10 matches order 1.
Custom SPD Parameters Without Supplier Dependency
Custom voltage grades, energy ratings or non-standard configurations are achievable without waiting on an external supplier's catalogue or qualification timeline. Engineering changes are implemented entirely in-house.
Unit-Level Traceability for Audit & Warranty
Every finished SPD traces to its production batch, electrical test records and raw material intake — supporting warranty claim verification, field failure investigation and quality audit requirements without recalling entire batches.
7–15 Working Days — No External Component Wait
No external component procurement lead time. Standard production is 7–15 working days from order confirmation — not subject to third-party component availability or external supplier MOQ constraints.
One 20,000m² Facility. Complete Production Chain.
TrilPeak's manufacturing facility houses both chip production and SPD assembly under one roof. Chips produced on-site move directly into the SPD assembly line — with no external handling, no inbound inspection delay and no third-party component risk.
Vertical Integration FAQ
Does TrilPeak produce its own components for its SPDs?
Yes. TrilPeak produces MOV chips in-house — from raw zinc oxide through all production and testing stages. These chips are used exclusively in TrilPeak's own SPD manufacturing, ensuring complete quality control from raw material to finished device.
Why does in-house production matter for OEM buyers?
It provides batch-to-batch parameter consistency, enables custom electrical specifications without relying on external suppliers, and gives full production traceability from raw material to shipped unit — essential for quality audits and warranty management.
Can I audit the production facility?
Yes. Factory audits covering the full production chain — material preparation, forming, sintering, assembly and testing — can be arranged. Third-party inspection by SGS, Bureau Veritas or Intertek is also welcomed. Contact us to schedule →
Can TrilPeak produce SPDs with custom electrical specifications?
Yes. Custom voltage grades, energy ratings and configurations can be produced in-house for ODM projects. Engineering feasibility and lead time impact are confirmed at the project specification stage. ODM details →
