Connector plastic mold parts will usher in greater development opportunities
With the further development of 5G and new energy automobile industry, there is an industry closely related to it, that is, the connector plastic mold fittings industry. Connector plastic mold fittings industry is located in the middle and upper reaches of the manufacturing industry, the downstream market is mainly for automotive, communications, consumer electronics, industry, defense, etc., of which automotive and communications applications occupy a major position.

Connector Plastic mold fittings, also known as connectors, plugs, sockets. Its role is to be blocked or isolated in the circuit between the circuit, bridge the communication, so that the current flow, so that the circuit to achieve the intended function.

Under the conditions of different application objects, frequencies, powers and application environments, connectors have a variety of forms and structures, which also makes them characterized by multiple varieties and small batches, especially in the automotive and communication application industries. At present, under the impetus of 5G and new energy vehicles, connector plastic mold parts will usher in greater development opportunities.

From the segmentation point of view, the largest application market for connectors in the automotive and communications industry, accompanied by a new round of popularization and promotion of 5G, new energy vehicles, will inject new growth momentum for the connector market. Connectors are an important part of communication equipment, mobile communication base stations, base station controllers, mobile switching networks, joint support nodes have to use a large number of connectors with different specifications and roles, such as RF connectors, power connectors, backplane connectors, input/output connectors, printed circuit board connectors and so on. According to the data published by Bishop & Associates 2019, the value of connectors used in the field of communication and data transmission accounts for 22% of the overall connector market.

Overall, the connector market size has basically maintained a continuous growth trend. Driven by emerging industries such as 5G communications and new energy vehicles, connector products have also begun to develop in the directions of electrification, high frequency and high speed, miniaturization, intelligence and precision. Facing increasingly stringent requirements and a massive processing market, the manufacturing process of connectors will surely enter a new round of upgrades.

Difficult to process, very complex structure, high process requirements

Connector mold parts structure on the numerous groove corners, tiny and complex, is the most important processing difficulties in its manufacture, the processing of clear corners, fried edges, dimensions, surface roughness have strict requirements. The current connector mold processing mainly has the following characteristics: high processing accuracy requirements: a mold is generally composed of concave mold, convex mold and mold frame, some may also be a multi-piece collocation module. So the combination of the upper and lower molds, inserts and cavities of the combination of the module are required to have a high degree of machining accuracy between the collocation. The dimensional accuracy of precision molds often reaches μm level; complex surface: some products, such as 5G base station connectors, automotive connectors, cell phone backplane connectors, etc., the shape of the surface is a combination of a variety of curved surfaces, so the mold cavity surface is very complex;

More processes: mold processing mainly used in milling, boring, drilling, reaming and tapping threads and other processes; corrosion and wear resistance: metal structural components, contact parts surface treatment layer may produce galvanic corrosion, affecting the connector’s physical and electrical properties, need to have good corrosion resistance. Connectors are inserted and pulled out once for a cycle, in the repeated cycle, to ensure that the connector wear resistance; high efficiency requirements: connector molds are mostly small pieces of multi-species, short lead time. With the increasingly stringent processing requirements, the processing process should not only meet the high performance indicators, but also pay more and more attention to high-efficiency manufacturing.

Processing method: EDM, increase speed, maintain accuracy, maintain stability

In view of the processing difficulties such as material diversity, structural complexity and dimensional accuracy of connector molds, EDM is an important process method. Electrical discharge machining directly uses electrical energy, chemical energy, light energy and sound energy to process the workpiece to achieve certain shape, size and surface roughness requirements.
Through high-speed pulse power supply (ISPG), it ensures uniform surface finish and minimizes electrode loss to make the sharp corner effect more perfect.https://jcmoldparts.com/products/characteristics-of-connector-mold-accessories/
