Rotomolding products are simple and practical, which is a big advantage, but it also brings some deficiency to the technology. For example, the inner part of products is prone to produce bubbles, and the surface is easy to become empty; products are easy to bend, shrinkage and change color, etc. These...

For each kind of plastic and plastic parts, there is a temperature limitation on mold surface, once exceed the limitation, one or more adverse effects may appear. The higher temperature of mold is, the smaller flow resistance will be. In a number of injection molding machine, this naturally means faster...

Applicable for various, small batch production of plastic products: due to the fact that rotational molding is not affected by external force, the mold is simple, low cost and easy to fabricate, for this reason it is easy to exchange products. Besides, roll-plastic equipment also has great mobility,...

Injection molding hangers mean plastic hangers, mainly made through injection molding process. Since environment of most plastic hangers production workshop is terrible, if the machine has low anti-interference ability, phenomenon like electronic feet beat, chaotic of machine’s program, malfunction...

Design steps for mould sample are as following: a. According to the mould drawing, analysis and understand the design intent, structure features and technical requirements of the mould and take these into consideration when designing model. b. Determine the locating basis of measurement position and...

1. Metal trap Transport crush waste by pipeline, using metal trap to separate metal chips of 0.75-1.2 mm diameter in the process of transmission. 2. Electrostatic separator Crush the adulterant and put it into electrostatic separator, taking advantage of different electric properties of metal and plastic,...

Rotomolding is a kind of hollow plastic molding process, also called as rotational molding or rotary forming. Process of rotomolding is to put the mold plastic powder into mould, then heat the mould and make it rotate continuously along the two perpendicular axes. Under the effect of gravity and heat,...

With the development of rotational molding, application range of rotational molding products is increasingly expanding, now rotational molding products are widely used, and here are some representative application examples as follows. Rotomolding containers This kind of plastic products is widely used...

Rotomolding, called as rotational moulding or rotary forming, is a kind of plastics molding process technology with long history. It’s reported that the pioneer technological core of rotomolding probably derives from Qing Dynasty. But plastic rotomolding originated from England, with the first...
