Stamping Part Process Flow:
Progressive metal stamping is a metal processing method that includes punching, coining, bending and other processes and automatic feed systems. Through the feed system, the metal raw materials are pushed from the coils to the respective stations of the stamping die and are sequentially stamped and formed by the punching machine. At each of these stages, the metal undergoes one or more stampings to obtain the desired shape of the final product. In the final stage, the finished part is cut and ejected.

At first, the metal stamping die is placed over the reciprocating metal stamping press. The press then moves up and the top die moves in synchronization with it. This action allows the material to reach in. As the press then moves down, the die gets closed and the stamping operation is carried out. With each one of the press'stroke, the completed part of die of stamping on metal gets removed from the die.

It is necessary to ensure precise placement of the strip so that it does not get misplaced in any way during its course of travel from one station to the other. This however cannot be provided by the feeding mechanism and hence, 'pilots'are used for proper placement of strips. These pilots can either conical or bullet-like in shape.

Here, we have diverse range of capabilities in metal production. This ranges from gauge to other high-strength components. We are readily equipped and prepared to handle any production volume demanded from our clients. You can send in the drawing samples to us and we would send our quote for custom metal stamping services accordingly.

Injection Molding Process Flow:
Shunjie Electronics has many years of experience as a custom plastic insert molder.

Plastic injection insert molding is a plastic injection molding process in which thermoplastic material is molded around an insert piece or pieces placed in the plastic injection molding cavity, resulting in a single strongly bonded, integrated assembly, with the insert or inserts encapsulated by the plastic. Inserts can be metal, another plastic, ceramic or just about any substance that can withstand the plastic injection molding process.

Some of the first insert molding applications were for placing threaded inserts into molded parts and encapsulating wire plug connections on electrical cords. Current custom insert molding applications are wide ranging with few limitations on material combinations, including:
  • Medical devices and instruments, such as needle hubs and tube valves
  • Knobs for appliances, controls and assemblies
  • Encapsulated electronic devices and electrical components
  • Military equipment
  • Threaded fasteners
  • Encapsulated bushings, tubes, studs, and posted
Plastic injection insert molding is an effective alternative to assemblies manufactured using soldering, adhesives or fasteners, with benefits including:
  • Reduced assembly and labor costs
    Molded as one assembly
  • Reduced size and weight
    Insert molding allows for reduction of part size and weight because parts are joined with strong, light weight plastic resin and fasters or connectors are eliminated.
  • Improved component reliability
    Insert molding of components ensures proper alignment, prevents loosening and the plastic resin can provide improved resistance to vibration and shock
  • Improved part strength and structure
    Insert molding combines the physical strength of the plastic resin and insert to produce one seamless plastic part
  • Enhanced design flexibility
    Custom plastic insert molding allows for almost unlimited configurations and material combinations
  • Consolidation of components
    Insert molded components enable part and inventory cost reductions
Another application of the plastic injection insert molding technology is in-mold decorating and in-mold labeling, in which decorated or printed film is inserted into the mold cavity and the plastic resin injected against the film, resulting in a labeled or decorated part that is durable and cost effective.

Proper mold design and construction are critically important in insert molding to maintain part tolerances and tooling reliability. Shunjie Electronics often employs automation in the insert molding process for fast and precise placement of inserts.

From concept to delivery, learn more about the competitive advantage Shunjie Electronics provides OEMs with custom plastic injection molding and insert molding, through early supplier involvement in the design and engineering phase, design for manufacturability, project management, in house mold building, material selection support and via our global locations.
