Laser Cutting vs CNC Punching: When to Use Which
Fiber laser excels at complex contours and thin sheets; CNC turret punching wins on high-volume repeatability with formed features. Choose the right process.
About WERIX MetalJulia takes a product from the first sketch to a sheet metal design that can actually be made. She sits between the customer’s concept and our press brakes — modelling enclosures and brackets in CAD, running early DFM passes, and choosing the material and finish that will still look right two years down the line. Author of the WERIX Metal engineering blog — DFM design rules, material selection and sourcing guides.
Fiber laser excels at complex contours and thin sheets; CNC turret punching wins on high-volume repeatability with formed features. Choose the right process.
Choosing the right alloy affects cost, manufacturability, corrosion resistance, and performance. Compare common sheet-metal materials with data in this guide.
Material waste, over-tolerancing, and poor process selection are the top cost drivers in sheet metal. Here is how to eliminate them and cut your per-part cost.
Sheet metal fabrication and CNC machining serve different geometries, volumes, and budgets. This data-backed comparison covers cost, tolerance, materials, and lead time to help engineers pick the right process.
Design-for-manufacturing rules for sheet metal — minimum hole sizes, bend radii, edge distances, tab-and-slot design, and common mistakes that cause scrap and rework.
304 stainless and 5052 aluminum are the two most-specified alloys in sheet metal fabrication. Compare properties, cost, weldability, corrosion resistance, and surface finishes to pick the right material.
One builds a layer on top of the metal, the other converts the surface itself. Here is how powder coating and anodizing compare on cost, durability and repairability.
Zinc is a thin sacrificial coating that protects steel even when scratched, for a few cents. Nickel is harder, brighter and lasts 1,000+ hours in salt spray, but costs 3-5x more. Here is how to choose between the two plating finishes.
Sheet metal gauge is a thickness scale where a higher number means a thinner sheet. Here is the steel gauge-to-mm chart, why aluminum and stainless read differently, and how to pick the right gauge for your part.
Minimum bend radius is the tightest curve you can form without cracking. It scales with thickness — here is the chart (in multiples of thickness) for steel, aluminum, stainless and more, plus how to choose the right radius.
Sheet metal weight = length × width × thickness × density. Here is the formula, a density table for steel, aluminum, stainless and more, a worked example, plus our free weight calculator.
One bends beautifully and shrugs off salt water; the other is stronger and machines like a dream but cracks when formed. Why the bend, not the datasheet, decides the alloy for sheet metal parts.
One is the everyday workhorse; the other adds molybdenum to fight chlorides at a premium. Here is where 316 genuinely earns its cost — and where 304 quietly does the same job for less.
Incoming Material
Each batch of raw sheet metal checked for thickness, grade, and surface finish before production begins.
In-Process Check
First-article inspection and random sampling at every workstation: laser, bend, weld, stamp.
Final Inspection
Dimensions checked against customer drawings. Precision instruments used for tight-tolerance parts.
Shipment Audit
Packaging, labeling, and surface protection inspected before dispatch. Each batch traced.
TomSenior Process EngineerWERIX 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.
WERIX has served 5,000+ clients across 30+ countries since 2015, delivering 10,000+ prototypes with a 98% on-time delivery rate.
Yes. We welcome factory audits in person or via live video call. Our facility in Changping, Dongguan is open by appointment.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
