Rubber plastic fiber molding technology basic introduction: rubber moulded plastic fiber is also called pressure molding, this method is to mould plastics (powder, granular materials, debris, or fiber presoak material, etc.) on Yin model cavity, close male mold, with the aid of pressure and heat, melt material fills the cavity, the formation and cavity of the same products. After heat curing, demoulding after cooling, then made of moulded products, including rubber moulded plastic fiber must be used bridging mechanical rubber plastic fiber moulding machine.
Rubber moulded plastic fiber is suitable for the thermosetting plastic molding process, such as phenolic resin, urea formaldehyde, amino plastics plastic, unsaturated polyester, epoxy, polyimide, organic silicon, etc, and some thermoplastic plastic products processing and production.
Rubber plastic fiber molding molding technology of the main advantages:
1) high efficiency, easy to realize specialization and automation production.
(2) product size precision, good repeatability;
(3) the surface is bright and clean, without secondary modification;
(4) can be a molding complex products;
(5) for mass production, the price is relatively cheap.
The shortage of the moulded rubber moulded plastic fiber in mould manufacturing complex, investment is bigger, plus pressure machine, the most suitable for batch production of small and medium-sized composite materials products. As metal processing technology, manufacturing level and continuously improve the performance of synthetic resin process and development of the press tonnage and mesa size increasing, the molding temperature and pressure of moulding material is relatively lower, makes the size of the moulding products gradually to the large-scale development, has now can produce large auto parts, tub, whole toilet components, etc.
Mould pressing craft rubber moulded plastic fiber as reinforced material and moulding material varieties of state can be divided into the following several kinds:
1) fiber material moulding method is through the premixed or presoak fibrous moulding materials, into the metal mold, under certain temperature and pressure molding method of composite material products. The method is simple, widely used. According to the different on the specific operation, a premix mold and presoak moulded method.
(2) broken fabric moulding method will be soaked in resin adhesive liquid glass fiber cloth or other fabric, such as linen, organic fiber cloth, asbestos cloth or cotton cutout cut into pieces, and then in the metal mould heating extrusion forming composite materials products.
(3) fabric moulding method will be made in advance in the shape of a 2 d or 3 d fabric impregnated resin adhesive solution, and then into the metal mould heating extrusion forming for composite materials products.
(4) laminated moulded method will pre soaked in resin adhesive liquid glass fiber cloth or other fabric, cut into the required shape, and then in the metal mold integrated by heating or pressure molding composite material products.
(5) coil compression molding will pre soaked in resin adhesive solution of continuous fiber or cloth (with), through special winding machine provide a certain amount of tension and temperature, wind on the mandrel, add the mold for heating pressure molding composite material products.
(6) sheet plastic moulding (SMC) method to SMC sheet according to the requirements of products such as size, shape, thickness cutting blanking, after then multi-layer sheet composite in the metal mould heating forcing molding products.
Cruelly preforming billet mold method to cut short fiber manufactured similar in shape and size of preform billet, put it in the metal mold, and then to the mold injection preparation good adhesive (resin mixture), formed under certain temperature and pressure.
