The application of thick sheet blister molding in passenger cars

The application of thick sheet blister molding on the bus, with the rapid development of the transportation network, the demand for buses is growing, while the requirements for safety and comfort of buses are also increasing. The beauty and luxury of the interior parts have become one of the important signs of high-grade luxury buses.

Interior parts mainly refer to plastic parts, whose moulding process includes injection moulding, blister moulding, blow moulding and extrusion moulding. Injection moulding has high production efficiency, high precision and can mould complex parts, but the investment cost of moulds is large, product updates are slow and the size of parts is limited by the specifications of the moulding machine, therefore, the application of injection moulding on buses is mainly for complex parts such as instrument panels, air conditioning vents and parts that require precise fit. Suction moulding, on the other hand, has small mould input costs, is suitable for the production of large-sized parts, and is suitable for products that are updated quickly, but the size accuracy is not high and the production efficiency is low. As the interior of the bus is mainly large cover parts, the accuracy requirements are not high, and the production of the bus itself is not high, a general annual production of a few hundred units, coupled with the fact that customers often put forward various requirements for the internal configuration of the car, the size and appearance of the parts more or less change, so the blister moulding process is used more in the interior of the bus parts. Blow moulding and extrusion moulding are all used to produce plastic parts with specific requirements and are less applicable in the field of bus interiors.

Blister moulding can be divided by process into two types: sheet blister moulding and soft skin blister moulding. The material used for blister moulding is mainly acrylonitrile-butadiene-styrene (ABS) she
