WELDON Short History Share
WELDON was established in 2006 by Weldon, At the beginning, we mainly sold advertising products, but we face many problems, such as quality, delivery time, etc.Later, by chance, we bought our first CNC punching machine, At that time, we could only do some simple product processing, but we guarantee the quality and delivery time,Slowly we continue to upgrade and optimize. At present, we have a factory building of 7,000 square meters, nearly 30 imported equipment, and the most advanced sheet metal production technology. Made by WELDON Trustworthy.
WHAT IS SHEET METAL FABRICATION?
Sheet metal fabrication is the process of turning flat sheets of steel or aluminium into metal structures or products, by cutting, punching, folding and assembling. Sheet metal can be cut, bent or stretched into nearly any shape, which is generally done by cutting and burning the metal.
Sheet metal manufacturing is suitable for a range of metal materials. Such as Steel, Stainless Steel, Aluminum, Copper, and Brass. In daily life, products manufactured by sheet metal processing are everywhere, including large equipment casings and even home appliance or smaller parts like brackets or enclosures.So it’s tied to us.
A GUIDE TO SHEET METAL DESIGN PROCESS
Most people do not have a good understanding of the basic steps involved in sheet metal processing and manufacturing. Lack of basic knowledge will lead to the production of products that fail to meet their own requirements. Sheet metal processing usually requires multiple processes and requires a professional production team. and tools to get the job done successfully.
From start to finish, the metal fabrication design process includes:
The Idea
The formation of each project comes from an idea. Sheet metal processing is same. The project needs to start with the designer’s idea. We have a professional design engineer team. You can share your idea with us, and we will design; or we can cooperate with you to Design, for example, when designing 3D models, we will provide professional advice (wall thickness, bending size, hole direction, bending allowance, etc.)
Start making production drawing
Once the 3D modeling is done we need to start making the actual production drawings. The engineer needs to understand the whole product first and make blueprints. These blueprints will define the sheet metal specifications needed to make the initial drawings.
Initial sample making
For new products, we will first produce the first samples. After the production drawings are completed, we have a professional production system and send the drawings directly to the production workshop.Drawings usually include all manufacturing information, such as material selection, surface treatment, etc.
At the same time, the professional craft production master will do a secondary review of the drawings to ensure that the drawings drawn by the engineer meet the production process requirements.
After the second confirmation of the drawings, we will start the first sample production. During the production process, we will also carefully observe and record the problems that may occur in the production process. After the production is completed, we will have a professional quality inspection department to conduct inspections. Seal the sample after passing the inspection.
Mass Order Production
A prototype that passes testing and meets the required specification will go into full part production. After the production is completed, the quality inspection department will do inspection, and the qualified products can be shipped out, and the inspection qualification report needs to be provided when leaving the warehouse. Next, let us introduce the production process.
Sheet Metal Fabrication Process
We will formulate different production processes for different products. The main production processes are as follows:
Cutting
Cutting is usually the first step in sheet metal processing, and the rectangular material will be cut to the required size according to customer drawings. WELDON has two precision large imported laser cutting machines,Laser cutting enables high precision (+/- 0.1 mm) and saves time.
Sharp Remove
After the blanking is completed, there will be some fine burrs on the surface of the product. Weldon has a deburring machine that can easily remove the burrs. The surface of the product will not be scratched, making it safer and more beautiful.
Stamping
Stamping is a cold-forming method that transforms flat metal blanks into various shapes. The process uses a tool and die, which, when impacted, change the form of the metal through the use of shear pressure.It encompasses punching, bending, as well as embossing. It also incorporates flanging, which entails swiping the sheet of metal in such a way as to form flanges. WELDON owns an imported CNC punch machine，We also have many ready-made molds for punching, shutters, convex hulls, etc. The ready-made molds can be used by customers for free, saving mold costs.
Bending
Bending, as the name suggests, is about bending parts. We have 5 imported precision bending machines and many ready-made bending dies, which can save customers a lot of time and costs.
Welding
Welding means welding the parts together is a very critical step. It requires the precision and firmness of the packaged product size. Usually during welding, we will do a lot of welding tooling for positioning to ensure that the size meets the requirements. A wide range of welding techniques is available, including spot welding,stick welding, MIG, and TIG. We will choose different welding methods for different products.
Polishing
After welding, there will usually be welding scars and burrs on the surface. We will polish it to ensure the surface is beautiful and smooth.
Surface Treatment
For products with surface requirements, we will do surface treatment, such as spraying, galvanizing, etc.
We have our own powder coating line. We can customize the color as long as the customer provides the RAL Number, which is very convenient. At the same time, we will also phosphatize the product before spraying, remove oil and grease, and the product after phosphating treatment. , the adhesion of plastic powder is greatly increased, which ensures the quality of powder coating
Assemble
Products that need to be assembled, such as finished products, will be assembled according to the requirements of the drawings.
Inspection
In fact, our inspection process has always been there, we will inspect during production, re-inspect before surface treatment, pre-assembly inspection, pre-packaging inspection, which means that each item will be inspected four times.
At the same time, we also have an intelligent visual projection detector. When the cutting is completed, we only need to place the product on the ceremony to identify whether the size is consistent with the drawing to ensure the accuracy of the product.
Package
After the product passes the inspection, we will package it. There are many ways of packaging. We have wooden box packaging, carton packaging, pallet packaging, etc. Our engineers will design packaging for customers according to different products. The main issues we consider when designing packaging It is how to better protect the product, followed by saving packaging space and thus saving shipping costs.
Shipping
We provide one-stop service, we have a professional logistics team, which can provide the most affordable shipping and the fastest shipping time for you.
