Turnover Box Mould

50L Turnover Box Rotational Mould Product Discription The outward convex hole is actually a protruding platform formed on the rotational molding product, which requires the design of the corresponding parts of the mold. Because the the convex platform is perpendicular to the adjacent walls, it is easy to form a bridging phenomenon between the raw materials and powder during forming if the space is too small. So, the space of the convex platform should be large enough with the

50L Turnover Box Rotational Mould Product Discription Although rotational molding is carried out without pressure, there will be many problems to affect the product quality and mold safety if there is no vent on the mold. When the mold is heated, the air in the mold will expand and some volatile water and gas will expand and release after the melting of raw materials in the mold. If there is no mold hole, the pressure in the mold will gradually increase to make it difficult

50L Turnover Box Rotational Mould Product Discription Low-density polyethylene (LDPE), polymerized with organic peroxide as initiator under high pressure of 100~300 MPa, belongs to the first generation of polyethylene. So it is also called high-pressure polyethylene. The density of LDPE is generally in the range of 0.910~ 0.925g/cm3. The crystallinity of LDPE is about 5%~65%, and the melting point of LDPE range from 105℃ to 125℃. It has good softness, extensibility,

50L Turnover Box Rotational Mould Product Discription When the product molding stage enters the cooling stage, the cold and hot air inside and outside the mold cannot be exchanged and the cooling process of the product becomes longer and slower if there is no mold hole, which not only greatly reduces the production efficiency but also increases the possibility of shrinkage and warpage deformation of the product. Product Parameter Shaping type Turnover Box Mould Mold life 3

50L Turnover Box Rotational Mould Product Discription Since the corner of rotational molding products cannot be designed as sharp edges or angles, how to design the corner? Generally speaking, the angle of rotational molding products should be determined according to different kinds of raw materials. For example, the minimum angle of nylon with good fluidity should not be less than 20 ° and the angle of polyethylene and PVC products should be at least more than 30 ° while the

50L Turnover Box Rotational Mould Product Discription For some larger molds and products with more molten materials, especially for the open flame direct fired equipment, the pressure in the mold increases if there is no mold hole, which will lead the mold to expand and explode if the pressure is big enough. Product Advantages The case is of large volume, light structure and general purpose. The product made of high-quality plastic materials is applicable for the storage of

50L Turnover Box Rotational Mould Product Discription Rotomolding process is also called rotary molding and rotary casting molding. It is a thermoplastic hollow molding method. Rotational molding is a versatile process for making a variety of hollow plastic parts. The rotational molding process utilizes heating and rotation along two axes to produce a single hollow part. The molten plastic is injected into the rotating mold, and the centrifugal force forces the molten plastic

50L Turnover Box Rotational Mould Product Discription The setting of air vent on the rotational mold can not only balance the pressure inside and outside the mold, reduce the bubble pinhole phenomenon of the product, speed up the cooling time but also reduce the temperature difference between inside and outside of the product, reduce the shrinkage deformation and warpage phenomenon, which is helpful to improve the quality of the product. It can also make operators and mold
