Can one company in China make good parts, at a fair price, on time? Most buyers ask this before they order.
Dechen Metal Machining (DC) has made metal parts since 2013. It has delivered more than 1,000 custom sheet metal fabrication projects to companies around the world. It learned one big lesson from this work. A part should only be as exact as it needs to be. More accuracy than needed adds cost.
This guide shows how DC makes parts and what metals it uses. You will also learn about price, speed, quality and common buyer questions.
China is a strong choice for custom sheet metal fabrication. It works best when one supplier can quote fast, deliver on time and prove its quality. DC offers sheet metal laser cutting, CNC bending, welding and finishing, all from one company. It sends a firm price quote within 24 hours. Parts can be ready in as little as 5 to 10 days. DC’s full company name is Cangzhou Dechen Metal Products Co., Ltd.
What Is Custom Sheet Metal Fabrication?
Custom sheet metal fabrication is the process of making parts from flat metal sheet, based on your own drawing. The work includes cutting, bending, joining and finishing. Each step can be used alone or together.
The right mix depends on the part’s shape and use. Unlike ready-made parts, every size, hole and bend matches your exact design. Common examples are custom sheet metal brackets, sheet metal panels, chassis and enclosures.
Sheet Metal Fabrication Process Steps
| Step | What Happens | Common Methods |
| Blanking | Flat shapes are cut from the sheet | Laser cutting, turret press, waterjet cutting |
| Bending and forming | The flat piece is shaped | Press brakes, folding machines, stamping units |
| Assembly | Pieces are joined together | Welding, riveting, hardware insertion, adhesives |
| Finishing | The surface is coated or treated | Powder coating, plating, anodizing |
Why Do Global Buyers Look to China for Parts?
Global buyers look to China for custom sheet metal fabrication. One good supplier there can often do the whole job. But quality is not the same in every factory. This is true even for simple custom sheet metal parts. So do not just pick a country. Pick the right partner.
Three Tests to Apply to Any Supplier
- Is the price quote fast and easy to understand?
- Can they keep the delivery date?
- Can they prove their quality with records?
DC focuses on four main ways to make metal parts. These are stamping, deep drawing, sheet metal and CNC machining. DC also says it can work with many metals that are hard to shape.
How Custom Sheet Metal Fabrication Works at DC
DC’s custom sheet metal fabrication service can make anything from one test part to small production runs. It uses fully automated machines for CNC laser cutting, CNC punching, CNC panel bending and laser welding. It also uses traditional methods.
Laser Cutting and CNC Punching
Blanking is the first step. Here, flat shapes are cut out of the metal sheet. DC can use laser cutting, a turret press or waterjet cutting for this.
Sheet metal laser cutting works well for detailed shapes. A turret press uses a set of tools to punch holes. DC says its punching can be accurate to within ±.001″. This kind of accuracy is important for precision sheet metal fabrication.
CNC Bending and Forming
Bending turns the flat piece into its final shape. DC does this with press brakes, folding machines and stamping units. CNC sheet metal bending is run by a computer program. This helps each part in a batch get the same bend.
Welding, Riveting and Assembly
DC picks the right weld for each metal and design. It can use CO2, spot or argon welding. For example, a stainless steel sheet metal fabrication job may need a different weld than carbon steel. DC’s service page also names MIG, TIG and spot welding.
Too much welding heat can hurt thin metal or parts with tight tolerances. So DC keeps the heat as low as it can.
Rivets are another way to join metal. They can hold two different metals together. They can also reach spots other methods cannot. DC names three types: solid, semi-tubular and blind rivets. It also offers hardware insertion and adhesives.
Finishing That Arrives Ready to Use
DC can finish sheet metal panels and other parts with powder coating, plating or anodizing. These finishes protect the surface. DC also offers pad printing, silk screening, fastener insertion and edge rounding. Tumbling, countersinking and machining are on the list too.
The goal is simple. Your parts should arrive ready to use, or as close as possible. See the surface finishing options before you order.
Which Metals Can DC Cut, Bend and Weld?
DC works with 11 types of sheet metal. They include aluminum, aluminized metal, copper and stainless steel. DC also works with carbon steel, cold-rolled steel, high-strength steel and galvanized steel. Galvalume, hot-rolled steel and titanium complete the list. Every metal bends and welds a little differently. So DC picks the welding method to suit each one.
Stainless Steel and Aluminum Grades
Need stainless steel sheet metal fabrication? DC’s material range includes grades 301, 304, 316/316L, 321, 410, 420, 430, 440 and 17-4PH. For aluminum, the range includes 5052 and 6061, plus others. Look at DC’s full materials list to check that your grade is there before you finish your design.
What Really Drives the Price of a Sheet Metal Part?
The price of a sheet metal part depends on four things: how exact it must be (tolerances), design, extra work and order size. There is no set price list. DC’s engineers look at each drawing first. Then they send a firm price quote within 24 hours. It is a real price, not a rough guess.
Sheet Metal Cost Factors and How to Control Them
| Cost Factor | What DC Says | What You Can Do |
| Tolerances | Tight tolerances raise cost a lot; ±.020 is recommended for general use | Use tight limits only where the part needs them |
| Design | Engineers check specifications, materials and tolerances | Send full CAD files and notes early |
| Extra work | Finishing, fastener insertion and riveting from one supplier | Ask for a quote on the finished part |
| Order size | From a single prototype to low-volume production | Plan the right process before you scale up |
Prototype or Stamping: Which Fits Your Volume?
Fabrication works well for test parts and small orders. It does not need special tools (dies) made just for one part. Stamping does need dies. So it makes more sense when you order more parts. Precision sheet metal fabrication is a smart way to test your design first. Later, DC’s custom metal stamping service can handle bigger orders.
How Fast Can a China Fabricator Deliver?
DC can have sheet metal parts and assemblies ready in as little as 5 to 10 days.
From Drawing to Finished Part in Three Steps
- Send your 2D drawings or 3D CAD files. An NDA keeps your files private.
- DC’s engineers check your design, materials and tolerances. They send a firm price quote within 24 hours.
- Work starts with sheet metal laser cutting or CNC punching. Bending and finishing come next.
This speed makes sheet metal prototyping easy. Your team can test a part, change it and try again quickly. One more tip: ask if this time includes shipping. If not, add shipping days to your plan.
What Backs Up DC’s Quality Promise?
Three things back up DC’s quality: a big factory, many years of work and written quality promises. The company started in 2013. It does its own research, production and sales. Its factory is over 10,000㎡ in size. It has more than 80 high-precision machines. Read Dechen Metal’s company profile to learn more.
DC’s quote page makes three promises. First, it fully follows ISO 9001 standards. Second, every material can be traced and comes with certification. Third, your designs stay private under an NDA.
What Do ISO 9001 Standards Mean for Buyers?
ISO 9001 is the global standard for managing quality. It is set by the International Organization for Standardization (ISO). Material traceability means you can trace each batch of metal back to its records. This helps when custom sheet metal parts must pass a customer’s quality check.
Which Brackets, Panels and Enclosures Does DC Build?
DC’s past sheet metal projects include body panels, chassis, enclosures, cases and brackets. It has also made office and kitchen equipment. The jobs range from custom sheet metal brackets to full sheet metal panels and housings. All of this needs precision sheet metal fabrication. Each piece must fit well with the parts around it.
Industries DC Serves With Sheet Metal
DC makes sheet metal parts for many industries. These include aerospace, lighting, automotive, food and drink, electronics, hardware and medical. DC also serves farming (agriculture). Want to see electronic housings? Visit DC’s chassis shells and enclosures page.
What Should You Check Before Placing an Order?
