Shenzhen Jinjue Industrial Co., Ltd. was established in August 2016. Before that, it was a professional supplier of precision electronic stamping dies, and later transformed into a professional ODM/OEM manufacturer dedicated to precision electronic hardware stamping. Jinjue is mainly engaged in and provides solutions for precision stamping parts for mobile phones and 5G communications; various types of radiator fin/heat sink stamping parts; high-voltage terminal stamping parts, etc. The mobile phone and 5G communication stamping parts produced by Jinjue include shielding cover, backlight, antenna shrapnel, mobile phone midplane, mobile phone camera decoration steel sheet, and mobile phone card holder steel sheet.

Jinjue implements the quality system ISO9001:2015, and continues to promote 6S management activities in the factory to provide customers with continuous high-quality products and services. As of January 2019, there are 6 high-precision presses (imported from Japan and Taiwan), with more than 30 employees and more than 10 professional and technical personnel; among them, 3 senior engineers with more than 10 years of design and R&D capabilities and rich experience in manufacturing molds There are 8 intermediate engineers, 6 engineers and technicians with professional mold maintenance skills.

The Jinjue team has many years of actual production experience accumulated in the precision stamping industry. It overcomes difficulties and is good at technically overcoming high-precision and difficult-to-complex hardware. The thickness of continuous stamping materials can reach 0.05-3.0MM, and the dimensional accuracy of product blanking can reach ±0.01MM. Actively participate in the preliminary design of precision metal stamping parts for customers' products to ensure that the development cycle of new products is shortened and the cost of mass production products is optimized. Especially with its own mold room and a team that manufactures precision stamping molds, Jinjue can provide a one-stop solution from design, mold opening, production, post-processing, and assembly/packaging. It can implement in-mold automatic tapping and molds. Technical requirements such as internal automatic riveting have saved customers a lot of time and cost.

The product materials used by Jinjue include but are not limited to beryllium copper (heat treatment required), titanium copper, phosphor bronze, stainless steel, spring steel, etc.; surface treatments that can be provided include but are not limited to gold plating, silver plating, nickel plating, tin plating, Ultrasonic cleaning of oil stains, etc.; packaging services that can be provided include but are not limited to tape and roll packaging, carrier tape packaging, blister box packaging, and so on.

Jinjue is committed to becoming the world's most professional supplier of electronic precision stamping parts, and it is our responsibility to assist customers in enhancing their competitiveness. We look forward to your consultation and cooperation!


Mobile phone 5G

Jinjue is mainly engaged in the production of precision stamping parts for mobile phones and 5G communications, and specializes in providing solutions for precision stamping parts such as shielding covers, antenna shrapnels, mobile phone plates, mobile phone camera decorative parts steel sheets and mobile phone card holder steel sheets.

The shielding cover is mainly used in mobile phones, GPS and other fields to prevent electromagnetic interference (EMI) and shield the components and LCM on the PCB. The flatness of the shielding cover and backlight produced by Jinjue is strictly controlled within the tolerance range of 0.05mm to ensure its easy tinning performance and good shielding effect. We can provide stretch forming and one piece according to customer requirements and drawings. Two-piece solution with frame and frame + cover. Especially for the frame + cover two-piece shield, the SMT pick-up point of the frame part produced by Jinjue can be made into a separate type and embedded on the frame part, which is convenient for the later maintenance of the chips and electronic components inside. According to customer requirements, the materials used by Jinsheng are tin-plated steel, nickel silver, stainless steel, etc.; the available packaging methods with flat surface requirements on the bottom of the frame parts include carrier tape packaging, blister tray packaging, and the cover can be PE Bulk packaging.

The middle plate of the mobile phone, the steel sheet of the decorative parts of the camera and the steel sheet of the card tray are mainly the stamping parts of the assembly structure inside the mobile phone, which play the role of fixing and supporting the main board, the camera and the SIM card. Jinjue’s mobile phone mid-plates, camera decoration steel sheets, and cato steel sheets are mainly made of stainless steel and are designed and produced according to customers' concepts and requirements. At present, the existing mobile phone midplanes generally have the shortcomings of being extremely flexible and prone to degumming after being encapsulated. The medium plate designed and manufactured by Jinjue meets the requirements of various precision and strength. There are several buckles on the periphery of the metal plate body. The buckles are formed by bending a circular boss to the same side. After gluing, the plastic accommodates the groove or flange in it to avoid degumming. The decorative steel sheet of the camera can be continuously stamped and pneumatically cut according to the required quantity of the material strip, which is convenient for customers to achieve the requirements of continuous injection molding of inserts and so on. Cato steel sheet can also be pneumatically cut according to the customer's injection quantity requirements, which is convenient for injection molding of inserts. Jinjue will provide tinning and other post-processing as well as packaging services for different requirements according to customer requirements.

Hardware mould

Hardware molds are used in industrial production to use various presses and special tools installed on the press to make metal materials into parts or products of the required shape through pressure. These special tools are collectively referred to as hardware molds.

   The various tools and products used in our daily production and life, ranging from the base of the machine tool and the body shell, to a small screw, button and the shell of various household appliances, are all closely related to the mold. The shape of the mold determines the appearance of these products, and the processing quality and precision of the mold also determines the quality of these products. Because of the different materials, appearance, specifications and uses of various products, molds are divided into non-plastic molds such as casting molds, forging molds, die-casting molds, and stamping molds, as well as plastic molds.
