With the advent of electric vehicles, driverless technology and the era of new energy vehicles, the lightweight design of vehicles will be the inevitable trend of vehicle design, and it is plastic that can turn the lightweight design of vehicles into reality. The extensive use of plastics in the automotive industry will bring a new historical opportunity to the plastic industry and the automotive injection mold industry.
Behind the rapid development of automobile industry is the development of automobile mold industry. Especially in recent years, the development of the world automobile mold industry is changing with each passing day, and the demand for molds is also increasing. In a new car, about 500 injection molds are needed. In the developed countries of automobile industry, the market share of automobile products has exceeded 60%, and this trend continues to rise. It can be said that the proportion of injection mold in automobile mold is illegal, and its importance is self-evident.
Advanced technology of injection mold for automobile interior and exterior decoration
There is no essential difference between automobile injection mold and other injection mold, but it also has many characteristics of its own. Because the added value of automotive injection mold is generally high, many advanced technologies (such as sequence valve hot runner control technology, internal parting surface technology, low-pressure injection technology, etc.) have been developed and applied in automotive injection mold.
1. Sequence valve hot runner control technology (SVG Technology)
Sequence valve hot runner control technology (SVG Technology) is a new stage controlled hot runner technology, which solves the problem of appearance defects of traditional multi-point synchronous glue feeding products by controlling the glue feeding in sequence through the oil cylinder. It can effectively avoid the defects such as weld marks and cavitation in the automotive interior and exterior trim parts, reduce the flow length and reduce the forming pressure, and plays a great role in the automotive interior and exterior trim parts with strict appearance requirements.
2. Low pressure double-layer injection mold technology
The so-called low-pressure double-layer injection mold, also referred to as low-pressure injection mold, is a new type of injection mold technology, which directly completes the injection molding of the traditional parts that rely on manual coating and vacuum adsorption of the female mold and the male mold. The main principle of low-pressure injection mold is: the injection pressure is low, and the plastic flows on the cloth. When opening the mold, the cloth must be hung on the front mold hanging pin first, then the mold is closed, injected, and finally the parts are taken. The products produced by this technology have a special layer of soft cloth on the surface, which greatly improves the decoration, feel and aesthetics. Therefore, low-pressure injection mold technology is widely used in medium and high-end automobiles, generally used in automobile map bag skeleton, automobile ABC column and other parts.
