About WERIX
Is WERIX a factory or a trading company?
WERIX is a direct source factory — we own and operate all equipment in our 3,000+ sqm Dongguan facility. We are not a trading company or marketplace platform. Request a quote via the online quote form.
How many clients does WERIX serve?
WERIX has served 5,000+ clients across 30+ countries since 2015, delivering 10,000+ prototypes with a 98% on-time delivery rate.
Can I visit the WERIX factory?
Yes. We welcome factory audits in person or via live video call. Our facility in Changping, Dongguan is open by appointment.
Which quality system is WERIX certified to?
ISO 9001. The four-stage process — incoming material, in-process check, final inspection and shipment audit — runs inside that system, with batch traceability from raw coil to packed part.
Where is WERIX Metal located?
Our factory is at 35 Yuanjiangyuan Jintai Road, Changping Town, Dongguan, Guangdong, China — about an hour by road from Shenzhen Bao'an International Airport. All production, die making and final inspection take place at this address.
When was WERIX Metal established?
WERIX Metal was established in 2015 in Dongguan, Guangdong, and has manufactured sheet metal parts continuously since then — more than 11 years of production experience, with the same core engineering and production team.
Which manufacturing processes are performed in-house?
Laser cutting, CNC turret punching, shearing, CNC bending, TIG/MIG/spot/laser welding, riveting and hardware insertion, and metal stamping (progressive, transfer and compound dies, fine blanking and deep drawing) all run in our own facility, together with die design and die making in our in-house die workshop. Surface finishing is carried out by long-standing licensed partner plants to our specification and inspected by us before shipment.
Does WERIX support both prototypes and mass production?
Yes — one production path, not three suppliers. Prototype runs from a single piece with no tooling, low-volume production from 50 pieces, then NPI, then mass production. The same engineering contact and the same four-stage inspection system follow the project from the first sample to recurring orders.
Can WERIX provide FAI and inspection documentation?
Yes. We issue first article inspection reports (FAI), dimensional inspection reports, material certificates and, where the programme requires it, PPAP documentation. Tell us the documentation set your quality team needs and it is quoted together with the part.
Which countries does WERIX Metal serve?
WERIX Metal ships to more than 30 countries, with the largest customer bases in the United States, Germany, France, the United Kingdom and Australia. We work in English, Chinese, Japanese, Korean, German, French and Spanish, and quote in USD, EUR or CNY.
What certifications does WERIX hold?
WERIX Metal is certified to ISO 9001, the only management-system certification we hold; surface finishing is coordinated with specialist partners rather than run under our own roof. Every order runs through incoming, in-process, final and pre-shipment inspection. See the about page for the facility, team and quality system.
How long has WERIX been making sheet metal parts?
Since 2015 - more than 11 years of continuous production from the same Dongguan facility, with the same core engineering and production team. We have delivered 10,000+ prototypes and serve 5,000+ clients across 30+ countries.
Can WERIX sign an NDA before I send drawings?
Yes. A mutual NDA is signed before any file moves, and we can sign your template instead. Drawings are held on dedicated servers, never shared with other customers, and deleted on request at the end of a programme. Start a confidential enquiry through the quote form.
Does WERIX support both English and Chinese communication?
Yes. Engineers are available in English and Chinese, Monday to Friday 8:30-21:30 UTC+8, and we quote in USD, EUR or CNY. Most enquiries are answered within 24 hours by a senior engineer, not a sales bot.
Capabilities
What sheet metal capabilities does WERIX offer?
WERIX runs 17 processes across our own floor and our finishing partners: fiber laser cutting (±0.1mm), CNC bending (±0.5°), TIG/MIG/spot/laser welding, progressive die stamping (±0.01mm), deep drawing and assembly in-house, plus powder coating, anodizing and plating at long-standing licensed partner plants to our specification. Full process list on the capabilities overview.
Does WERIX handle both sheet metal fabrication and metal stamping?
Yes. WERIX is one of few factories offering both sheet metal fabrication (laser cut + bend) and metal stamping (progressive die, transfer die) under one roof with an in-house die workshop.
What tolerances can WERIX achieve?
Laser cutting: ±0.1mm. CNC bending: ±0.5° (±0.1° on new machines). Stamping: ±0.01mm with progressive dies. Welds for food-grade surfaces are produced to AWS D18.1 practice.
Can WERIX produce both a prototype and the production run?
Yes. Prototypes are laser cut and bent with no tooling cost, then the same part moves to turret punching or progressive die stamping once volume justifies the die. One factory, one quality system and one engineering contact cover every stage.
What is the maximum sheet metal size and thickness you can process?
Fiber laser cutting handles sheet up to 5 mm in production and 25 mm at reduced speed; CNC bending supports part lengths up to 2,200 mm with ±0.1° angle accuracy; turret punching covers sheet up to 6 mm. Tell us the part envelope and we will confirm machine fit.
Do you offer surface finishing and assembly in the same order?
Yes, on one purchase order. Hardware insertion, welding, gasket fitting and functional testing are done in-house; powder coating, anodizing, plating, brushing, sandblasting, silk printing and laser engraving are carried out by long-standing licensed partner plants to our specification and inspected by us. You deal with one supplier instead of five.
Is WERIX ISO 9001 certified?
Yes. WERIX Metal is ISO 9001 certified. The quality management system covers incoming material inspection, in-process control at every workstation, final inspection against your drawing and the shipment audit.
Which welding processes does WERIX offer?
WERIX offers TIG, MIG, spot and laser welding, all performed in-house on the same floor as cutting and bending. Spot and laser welding suit thin-gauge enclosures; TIG gives clean cosmetic seams on visible brackets. See the laser welding and TIG welding process pages for tolerances and typical parts.
Do you build and maintain stamping dies in-house?
Yes. Our in-house die design and die maintenance workshop designs, builds and services progressive, transfer and compound dies, so tooling changes never wait on a third party and the die stays matched to our own presses.
What is the largest sheet size you can laser cut?
Production fiber laser cutting handles sheet up to 5 mm thick and 25 mm at reduced speed, on beds sized for full-size sheet. For thicker plate or longer parts, CNC punching and press-brake bending cover the envelope - tell us the part dimensions and we will confirm machine fit on our capabilities overview.
Can WERIX deep draw parts?
Yes. Deep drawing produces seamless cylindrical and box-shaped shells from a flat blank in one progressive sequence, ideal for shielded cans, housings and covers where a welded seam would leak or rust. Send the drawing and we will assess draw ratio and required stations.
When should I choose laser cutting instead of CNC punching?
Use laser cutting for low-volume runs, complex profiles and parts with few repeated features — there is no tooling, so a 1-piece prototype and a 500-piece batch share the same setup. Move to CNC turret punching once the design is stable and the sheet has many identical holes, louvers, tabs or forms, because the punch hits far faster per feature at volume. The crossover is usually in the low thousands of pieces; see our laser vs punch guide for the full decision matrix.
What is the difference between laser cutting and CNC punching?
Laser cutting is a non-contact beam that cuts any 2D profile with no tooling and a 0.1 mm edge; CNC turret punching strikes shaped tools into the sheet, so it is faster for repeated holes and forms but limited to tool geometry. Laser suits prototypes and complex shapes, punching suits repetitive high-volume features. Both feed the same press-brake bending cell, so the part is finished on one floor.
Sheet metal fabrication or CNC machining — which for my bracket?
Choose sheet metal when the part is a thin-walled enclosure, panel, bracket or chassis from 0.3–6 mm stock — it is faster and cheaper to cut and bend than to mill a solid block, and far lighter. Choose CNC machining when you need thick sections, tight 3D tolerances or features sheet metal cannot form. Many parts use both: a machined insert in a fabricated housing. Our sheet metal vs CNC guide walks through the cost and tolerance trade-offs.
Laser cutting, CNC punching or stamping — which process for my part?
Start with fiber laser cutting for prototypes and low volumes, complex profiles or few repeated features — no tooling, ±0.1 mm edge. Move to CNC turret punching once the sheet has many identical holes, louvers or forms and the design is stable, because the punch hits far faster per feature. Move to progressive-die stamping above a few thousand parts a year, where ±0.01 mm repeatability and the lowest unit cost justify the die. All three feed the same press-brake cell, so the part is finished on one floor. See the laser vs punch guide for the crossover numbers.
