Technical and Process barriers of automobile connectors

Automobile connector is a medium and high-end connector product with high technical and process barriers.

First, the high requirements for Technical

The connector product itself has high process requirements, high technical content and high-quality requirements, which requires the manufacturer to have strong industry experience, R&D ability, process ability and quality assurance ability, and its R&D design ability is highly matched with the production and processing technology to adapt to the technological innovation and process innovation of product update iteration. There are many patent barriers to connectors. The latecomers also need a long time of technical accumulation and investment to bypass patents, and the threshold is high.

Second, the high requirements for Mold Development

From the production process of connector products, the main processes include precision injection molding, precision stamping, die-casting, machining, surface treatment, assembly and testing, involving material technology, structural design, simulation technology, microwave technology, surface treatment technology, mold development technology, injection molding technology, stamping technology, etc. The design and manufacture of die is the prerequisite for realizing the mass production of products. Its design level and manufacturing process determine the precision, yield and production efficiency of connector products.

Connector manufacturers usually need to support high-precision mold processing equipment, such as high-precision wire cutting, spark discharge machine, grinding machine, etc., which is expensive, and the precision mold manufacturing process is complex. Generally, it is single-piece production, the production cycle is long, and the cost is high, which also puts forward higher requirements for the financial strength and research and development strength of enterprises.

Third, the high requirements for Automation Equipment

 Precision stamping, injection molding and automatic machine assembly are the key to automatic production.

1) Stamping is a kind of cold stamping processing method. With the help of the power of the standard or special stamping equipment, the material is cut, bent or molded into the shape and size of the finished product specified by the mold, which is divided into two categories: separation/blanking process and forming process. Blanking can separate the stamping parts from the sheet along a certain contour line and ensure the quality requirements of the separated section; The forming process can make the sheet metal plastic deformation without breaking the blank, and make the workpiece with the required shape and size. The key of stamping process is how to produce products with high precision and complex shape at high speed and stably.

2) The average level of processing precision of injection mold in the industry is ± 10 microns, and the leading level can reach ± 1 microns. Manufacturers usually support automatic precision injection molding systems, which can realize automatic drying of plastic raw materials, intelligent absorption and feeding, and are equipped with robots or multi-joint robots to assist, realizing the whole process of unmanned operation and real-time monitoring, greatly improving production efficiency.

3) Automatic machine assembly can improve production efficiency and have scale effect while ensuring product quality and yield. The assembly efficiency and mass production scale of automata determine the enterprise cost.

The manufacturers that Typhoenix cooperates with are all supporting factories of existing automobile factories, with independent research and development capabilities, complex mold development and manufacturing capabilities, and large-scale automatic production.
