Sheet Metal Fabrication

We own the facility of various cutting technologies such as laser cutting, waterjet cutting, and plasma cutting. Our cutting services deliver high precision with the help of advanced machinery. We handle the calibration of these machines, ensuring each cut meets your tolerances requirements.

• Laser cutting is the most frequent technology of all the cutting we own, while we have experienced engineers for fine tuning the parameters such as focus condition, power and wavelength, route and beam angles etc.  

• Waterjet cutting is often used in cutting thick objects, such as metal blocks, stones or wood stock, because of its relatively low cost and energy consumption. JCL is good at creating clean and smooth waterjet cutting parts by our specialize machine and self-owned abrasives.

• Plasma cutting is a very good alternative to laser and waterjet cutting, especially when you need a fast and low cost cutting service for large size metal pieces. It generates much higher power and removal rate than laser, enabling the fast turnaround for sheet metal blanks and extra material removal. 

JCL owns more than 5 sets of press brakes in different tonnage, working length and stroke length. We can create a maximum 3000*6000mm size sheet metal part in our biggest machine and no more than 8mm thick blank with our largest tonnage machine.We recognize that bending sheet metal is as much about understanding material properties, we own our knowledge of producing multiple materials including types of steel, stainless steels. Aluminum, copper and brass, you can designate your special materials and our material expert is going to have a full data to analyze its properties and forming behaviors. In other words, our design engineer is familiar with the basic principles of metal bending, we can determine important parameters and specifications such as bending corner radius, bending directions, position alignments and blank sheet profiles etc.We will work with our customers closely to clear all the nuance for a simple and understandable design report. An ultimate precision with an acceptable cost and lead time is always our final goal. We guarantee a 7 days analysis report and minimum 15 days shipment with finest +/-0.1mm tolerances with our full support.

Aluminum extrusion is a very common forming technology for applications like machine customization, automotive components, construction and building and automation systems. Usually we need to design an extrusion die based on customers' drawings. This die is manufactured with a cross section profile, which basically is the design drawing, by wire cutting. JCL is able to take care of these tasks in house and machine the die with best tolerance with our machines. When the die is done, we need to install the die into an extrusion machine, where the aluminum ingot is going to be heated and pressed through the die to form the profile we want. JCL owns a full capacity of extrusion production with our partners and we also take care of post-processing of your parts such as features and end machining, surface finishing and packaging and so on.

JCL understands that our customers prefer to receive the final product with one stop service. Therefore, we have invested in complementary surface treatment equipment and collaborated with professional partners to establish a metal surface treatment processing line. With this setup, customers don't need to deal with multiple suppliers simultaneously. They can complete both the shaping and surface treatment of metal sheets in one place, significantly saving communication time and operational costs.

We employ a range of finishing techniques from sandblasting to remove surface imperfections to vibratory finishing for smoother surfaces. Moreover, our high-precision grinding and polishing machines provide a consistent and mirror-like finish. We offer a comprehensive range of coating solutions. Whether you require an anti-corrosion layer, a decorative finish, or a protective shield against wear and tear, we've got you covered. These technologies are painting, powder coating, plating, passivation, anodizing and vacuum coatings, we ensure each component receives a durable, uniform, and high-quality coat.

Welding is the inevitable way of sheet metal constructions in JCL, it's an expertise we are eager to serve for you. Our welders are adept at a variety of welding techniques, including laser, MIG, TIG, spot, flux and arc welding, ensuring we can tackle a broad spectrum of materials and project complexities. Generally, the cost ranking of all the welding technologies are spot, MIG, flux-cored, Arc, TIG and laser welding, but you need JCL advice to choose the best fitting one for your parts. Usually we need to know some basic information such as material, joining area, strength requirement and cosmetic specifications to make a decision. For example, laser welding is considered one of the strongest joining techniques for its high heat input and precision and spot weld is relatively weak, so we are leaning to choose laser welding for parts on automotive and aerospace but spot weld for connectivity of consumer products. However, we are guaranteed to use high-quality filler materials and the latest welding equipment, familiar with the surface treatment before and after the weld. Our post-weld inspections guarantee that each joint is not only strong but also free of defects.
