In recent years, the process of molding products with various composite materials has developed rapidly, with high performance-to-price ratio, low environmental pollution, and high productivity. It has been or is continuously adapting to the industrialization of automobile and bus industry, aerospace industry, chemical industry, bridge, communication and other fields. The need for development.
Composite materials are increasingly replacing traditional metal materials due to their well-known excellent properties and the increasing maturity of various processes. The compression molding process also occupies an important position in various forming process methods. In recent years, the process of molding products with various composite materials has developed rapidly, with high performance-to-price ratio, low environmental pollution, and high productivity. It has been or is continuously adapting to the industrialization of automobile and bus industry, aerospace industry, chemical industry, bridge, communication and other fields. The need for development.
The basic process of the molding process is to put a certain amount of pre-treated molding material into the preheated mold, and apply a higher pressure to fill the mold cavity with the molding material. Under a predetermined temperature condition, the molding compound is gradually solidified in the mold cavity, and then the product is taken out from the molding die, and the necessary auxiliary processing is performed to obtain the final product.
From the above process, the factors involved in completing the final product include the molding material itself, the compression mold, the pressurizing and heating hot press, the pressing process, the working environment and the auxiliary processing.
1. Work site: The work site should be well-lit, well-ventilated, well-equipped, and the environment clean and tidy.
2. Moulding material: Any form of moulding material should be evenly impregnated with resin in a predetermined ratio before being installed.
3. Pressing mold: In addition to ensuring the strength and rigidity conditions under working pressure, the mold used for the product should be considered to be able to apply pressure evenly to all parts and directions of the product.
4. Press: The size and tonnage of the press should be able to meet the requirements of the product, the selected material, and the mold structure. The temperature and pressure of the press should preferably have two modes of manual control and automatic control. The workbench or the upper and lower heating plates of the press should try to keep the work-piece level as far as possible to prevent the resin from flowing to the side. The temperature difference of the heating plate within the effective working range is controlled within ±5℃.
The molding machine independently developed and designed by PHP Pengda Hydraulics uses a pure oil-electric servo system to replace the traditional accumulator system, which is energy-saving and electricity-saving, and runs smoothly. The high-end European manufacturing standard technology makes the molding machine oil-proof, safe and reliable. The innovatively designed green environmental protection system creates a good production environment for our customers. And it is widely used in automobile lightweight, integral bathroom, aerospace, rail transit, urban construction, low-voltage electrical appliances and other industries, mainly used to realize the molding process of SMC, DMC, GMT, LFT-D and other products.
