Wenzhou, Zhejiang — ignition tools since 2000
Butane Torch Factory in Wenzhou, China
ZHENTANZHE is an integrated ignition-tool manufacturer based in Wenzhou, Zhejiang: we research, produce and export under our own roof, and we have been doing it since 2000. The company runs an 8,000 m² digital research and production base where every stage from order intake to packed cartons is tracked in one ERP system. For an import buyer that means one responsible partner instead of a chain of intermediaries — the people who quote your order are the people who build it.
The factory's product scope covers the four models presented on this site: three butane torches for kitchen, commercial and long-reach outdoor work, plus a portable five-star gas burner for camp cooking — a cooking appliance in its own category, not an ignition device. Development is joint with university labs, an AI inspection system runs on the production line, and every unit passes 20+ factory tests before packing. The company holds more than 100 domestic and international patents, including the design patent ZL202430152075.6 for the GF-8012 Standard Torch.
Location matters as much as the building. Wenzhou is one of the world's main ignition-tool manufacturing belts, which is why component sourcing, tooling skills and export handling concentrate here. The factory serves customers in 40+ countries with factory-direct OEM/ODM from 500 pcs (100 pcs for in-stock models) and 15–20 days of mass production after the deposit is received.
Products are professional tools, not toys: read the manual before use and keep them away from children. Fuel canisters are not included — purchase them locally according to your local regulations.

The industrial belt
Why Wenzhou builds the world's ignition tools
Wenzhou, on the coast of Zhejiang province, is one of the world's main manufacturing belts for ignition tools — the category that covers lighters, utility lighters and gas torches. The belt's scale is documented: at its peak, Wenzhou's metal-lighter industry is reported to have supplied around 80% of the global market and about 95% of the Chinese market (historical peak figures, per Jiemian News). The industry remains export-active today: in 2024, Wenzhou Customs inspected and supervised 2,600 export batches of lighter-category products with a total value of RMB 430 million (Wenzhou Customs data via Wenzhou Net, 2025-02). Decades of concentrated production have built up everything a torch project depends on: valve and seal suppliers, metal and plastics processing, tooling workshops, printing and packaging houses, and a workforce trained specifically in gas-tight assembly and flame testing. When a buyer asks how a 500-piece OEM order can move from sample to shipment in weeks, the industrial belt is a large part of the answer.
For sourcing teams, the belt's depth translates into three practical advantages. First, localization: the parts that decide torch quality — valves, piezo ignition components, nozzles, seals — are sourced close to the line, which shortens replacement and customization cycles. Second, skills: assembly and inspection know-how accumulates across the region, not inside a single plant. Third, export readiness: the region's trade infrastructure handles documentation, container loading and the compliance paperwork that pressurized-gas products require.
ZHENTANZHE operates inside this belt as an integrated manufacturer: self-developed products, in-house production on the 8,000 m² base and direct export to customers in 40+ countries. That combination — belt-level supply depth plus single-factory accountability — is what we offer buyers who need a dependable source rather than the cheapest quote.
Fuel canisters are not included with any product — purchase them locally according to your local regulations. Professional tool, not a toy. Read the manual before use. Keep away from children.
Inside the factory
Line, inspection and export handling
Three areas decide how your order turns out: the assembly line that builds it, the inspection process that filters it and the export handling that protects it in transit.
Inspection
An AI inspection system runs on the production line, and every unit passes 20+ factory tests — air-tightness, ignition, pressure and backfire among them — before packing.
Quality-control system
Export handling
Packed orders staged for container loading and shipped factory-direct to customers in 40+ countries, with documentation handled by the export team.
Export certificatesDigital & R&D infrastructure
ERP, AI inspection and university labs
Digital tools run through the whole base, not just the back office. They are the reason a custom order keeps its specification from first sample to final carton.
ERP across the full process
From order intake through material planning, production stages and shipment, every step is recorded in one ERP system — the record your order can be traced against.
AI inspection on the line
An AI-based inspection system works alongside manual checks on the production line, adding an automated layer to the 20+ item per-unit test routine.
How testing is organizedUniversity joint R&D
Product development runs jointly with university labs — the pipeline behind 100+ patents, including the GF-8012 design patent ZL202430152075.6.

Factory questions buyers ask
What does an integrated manufacturer mean for buyers?
Research, production and export run in-house under one roof: the factory develops its own products, manufactures them in its own 8,000 m² base and exports directly. There is no middleman between your order and the production line, which shortens communication and keeps specifications and test records in one place.
Can we visit or audit the factory?
Buyer inquiries about visits and audits are welcome. Contact us with your planned schedule and what you want to review — production areas, test procedures or export processes — and we will help arrange it.
Does the factory hold its own patents?
Yes. The company holds 100+ domestic and international patents, including the design patent ZL202430152075.6 for the GF-8012 Standard Torch. Joint development with university labs feeds the product pipeline.
Where do the goods ship from?
All products ship from the company's own base in Wenzhou, Zhejiang, China — an export-oriented manufacturing region with established container shipping connections. Shipping terms are agreed per order.
What are your order terms?
OEM/ODM orders start from 500 pcs (100 pcs for in-stock models), and mass production takes 15–20 days after the deposit is received. Sample fees are credited against bulk orders.
