01Surface Cleaning
Sheet metal parts need to be immersed in a cleaning pool to use acidic or alkaline solutions to remove oil stains and impurities on the surface. This step is to improve the adhesion of the coating on the surface of the workpiece so that the coating can be more uniform and the pass rate is higher.

Overall Assembly
Overall assembly is a service that assembles various spare parts using riveting, screws, welding, etc. The overall assembly is divided into fully automatic mechanical assembly and manual assembly. The former is more suitable for orders with hundreds of thousands of pieces and huge volumes, such as automobile assembly, while the latter is more suitable for small batch orders. Manual assembly requires the high proficiency of workers. Because experienced workers can improve the pass rate of finished products. Strictly managed factory assembly lines have higher assembly efficiency. Orders can be delivered in less time. HULK Metal's assembly line has advanced assembly equipment and experienced workers who can complete your order faster.
-
Sheet Metal Cutting
Sheet metal cutting is using tools such as plasma cutting machines, flame-cutting machines, water-cutting machines, laser cutting machines, and grinding wheel cutting machines to cut metal into the required shape and size. Choosing the right cutting tool can improve your sheet metal production process. When cutting thick metal plates of 20mm and above, choose a plasma cutting machine and choose laser cutting for metal plates of 20mm. Abrasive cutting is suitable for thinner and smaller metal plates. Our factory uses laser cutting because it has smaller cutting seams, smooth cutting surfaces, and high cutting surface precision, which can save material costs and labor costs in processing cuts.
-
Sheet Metal Machining
Many sheet metal parts need to be machined after stamping to further adjust holes, threads, and surfaces. Drilling, reaming, turning, milling, and grinding in mechanical processing can complete the above processes. Ordinary machine tools have more advantages in processing small and simple parts. CNC machine tools can save more labor costs when processing complex parts. During the solution formulation process, we will choose a more suitable process to reduce costs and shorten order lead time. Kindly contact us to obtain a more suitable solution for you and a more competitive quotation.
-
Sheet Metal Stamping
Sheet metal stamping is the process of installing a stamping die on a press to process metal sheets. Metal stamping can be divided into two processes: blanking and forming. Use blanking to retain the required parts and obtain stamped parts through bending, deep drawing, bulging, flagging, and other forming processes. There are also many types of stamping molds, including single-process molds, composite molds, continuous molds, and transfer molds. We will design a suitable stamping process based on your product drawings, produce stamping molds, and complete the order at the lowest cost possible while ensuring product quality.
-
Sheet Metal Welding
Sheet metal welding is the use of fusion welding, pressure welding, or brazing to weld two or more sheet metal stamping parts into a finished product or accessory for subsequent assembly. There are many types of welding. According to the melting energy, it can be divided into electric welding, chemical welding, mechanical welding, and laser welding. An experienced welder can complete higher-quality welds faster. Large batch orders can use our fully automatic welding machines.
SHEET METAL SURFACE TREATMENT SERVICES INTRODUCTION
Surface treatment is used to solve the problem that some sheet metal parts cannot be used for a long time in specific environments due to their metallic properties. Add layers that resist corrosion, oxidation, or wear to extend service life and enhance aesthetics. Below, we will use a certain amount of space to introduce the meaning and types of surface treatment.
-
Sheet Metal Surface Treatment
Surface treatment is the use of physical, chemical, electrochemical, mechanical, and other methods to cause chemical changes in the substrate or to coat the surface of the sheet metal part with another substance that has different mechanical, physical, and chemical properties from the substrate (such as metal, plastics, organic substances, inorganic substances, etc.) allow sheet metal parts to have corrosion resistance, wear resistance, and decorative performance requirements that can adapt to the use environment. Surface treatment suits sheet metal parts of all materials (aluminum, iron, copper, steel, and their alloys).
-
Surface Treatment Types & Application
Surface treatment can be divided into chemical, electrochemical, physical, mechanical, etc., based on the way to change the surface of the substrate.
Chemical Surface Treatment:
Make the substrate itself undergo chemical changes to convert compounds with better performance, or use a catalyst to cause a reduction reaction between the electrolyte and the substrate without current to deposit a coating on the surface of the substrate.
Common ones include electroless plating, chemical conversion coating (blue, phosphating, passivation, chromium salt treatment), electroless nickel plating, electroless copper plating, and CVD.
Electrochemical Surface Treatment:
Using the positive and negative electrodes, the swimming direction of ions in the solution forms a layer of other materials on the surface of the workpiece.
Common ones are electro-zinc plating, electrophoresis, anodizing
Physical Surface Treatment:
A surface treatment method that is completed without changing the properties of the substrate itself and the coating itself.
Common ones include hot dip plating, thermal spraying, hot stamping, surfacing, powder spraying, laser processing, etc.
Mechanical Surface Treatment:
Use machinery to change the surface physical structure of sheet metal parts to make their surface properties better and more beautiful.
Common ones include polishing, shot blasting, sandblasting, wire drawing, etc.
