Rotational Molding, also called rotomolding or rotocast, is a thermoplastic process for producing hollow parts by placing powder or liquid resin into a hollow mold and then rotating that tool bi-axially in an oven until the resin melts and coats the inside of the mold cavity. Next the tool is cooled and the part is removed from the mold.

• • 
    
    
     Four steps in manufacturing a rotational molded part
    
    
    1. Fill the mold with a polymer material
    
    
    2. Heat tool in oven to melt material
    
    
    3. Cool tool to solidifies the part
    
    
    4. Remove part from the tools
    
    
    
    Design & Manufacturing
    Rotational molded parts can be made out several different kinds of materials and have multi-layered walls. Unusual shapes can be produced as one part, that normally would have to be assembled from several parts.
    Rotomolding was actually invented in the 20th century, but didn't gain traction as a production process until the 1960s. Today, it continues to advance as a viable process for plastic part creation.

Shuo long TPE as a manufacturer, the high cost of land in Shenzhen have 10000W square meters of total area of ​​6000 square meters of factory space, 10 injection molding machines of large-scale manufacturers, is definitely your best choice.

Casting processing

tony

Cast molding casting process is generally not exert pressure on the less demanding strength equipment and molds for products small size limits within the article stress low. Thus, less productive investment, good performance can be obtained large parts, but a longer production cycle, must be machined after molding. On the basis of the traditional casting, derived perfusion, inlay casting, pressure casting, spin casting and centrifugal casting methods.  perfusion. This method of casting difference: finished product that is escaping from the casting mold; and perfusion mold is part of the preparation itself.  inlay casting. The various non-plastic parts placed in a mold cavity, and the injected liquid material cured together, so it encapsulated therein.  pressure casting.

 When casting exert a certain pressure on the material in favor of the viscous material into a mold, and shorten the filling time, mainly used for epoxy resin casting.  spin casting. After the material injected into the mold, the mold at a lower speed of rotation around the single-axis or multi-axis, the material distributed by gravity to the die cavity wall by heating, curing and stereotypes. For the manufacture of spherical, tubular and other hollow products.  centrifugal casting. The amount of the liquid material injected into the high-speed rotation around the single-axis, and the heated mold, the material will be distributed by centrifugal force to the walls of the mold cavity, by physical or chemical action cured tubular or hollow cylindrical articles. Monomer cast nylon parts can also be molded centrifugal casting method.

Extrusion processing

TONY

Extruded plastic extrusion processing, also known by hydraulic pressure in the non-rubber processing extruder to said extrusion mold itself pushed out. Refers to the mechanism of action of the material through the extruder barrel and the screw between the side heat plasticizing screw edges are pushed forward continuously made a processing method or semi-finished products of various cross-section through the nose.

In the chemical industry is also useful fiber extruder feed to spinnerets for melt spinning. Extrusion applied thermoplastics and rubber processing, ingredients, granulation, plastic materials such as filtration, continuous production, the manufacture of various products such as continuous tubes, profiles, sheet (or sheets), film, wire and cable package cover, rubber tire noodles, inner tubes tire tube, sealing strips, high production efficiency. In the production of synthetic resin, the extruder can be used as reactor, continuous polymerization and forming complete compression ratio in the rubber industry can be used in different extruders mastication of natural rubber compression extrusion machines of different materials than some different.

Principle:

Material from the hopper into the barrel, the rotation of a screw, and the screw through the barrel inner wall surface frictional shearing forwarded to the feed zone where loose conveyed forward while being compacted solid; in the compression section, the depth of groove lighter, more compact, while heating and screw and barrel inner wall of the friction shear material temperature rise starts to melt at the end of the compression section of the outer cylinder; homogenization section so that the material uniform, constant temperature, quantitative, constant pressure extrusion melt to die after forming, shaping get product

Why toy industry with TPR / TPE material can replace PVC

tony

Once upon a time, when it comes to soft toys, people do not consciously think of PVC toys. Shrunk, TPR soft toys in the ascendant, gradually leading the present and future of soft toy market. That TPR / TPE What's charm, can gradually replace PVC, flourish it in the toy industry, and so I could go on.

Saying soft PVC material of low cost, convenient and various molding, easy to color, soft touch. So consolidated the excellent performance of materials, natural became soft toy industry is the best raw materials. However, everything has two sides, PVC advantages and aura can not hide its shortcomings.

Currently most environmentally friendly PVC toys contain DOP, DEHP and other plasticizers and stabilizers environmental, environmentally friendly PVC thus produced in line with ROHS, non-6P and so on. But this kind of green PVC is not guaranteed to meet the EU related to the latest US REACH, SGS, FDA relevant testing standards, such as nonylphenol, polycyclic aromatic hydrocarbons and other testing. Also PVC halogen-containing chlorine, combustion releases toxic chemicals dioxins and so on.

TPR / TPE soft material, use of environmentally friendly plasticizer modified without adding toxic chemicals, free of halogen, burning non-toxic. Comply with ROHS, without 6P? P, excluding polycyclic aromatic hydrocarbons PAHs, excluding nonylphenol NP, excluding bisphenol A, in full compliance with EU EN71-3, EN71-9, American ASTM-F963 and other toys industry standards.
