Pigments will affect the rotomolding products in various aspects, including: shrink ratio, nontransparency, durability, light stability, impact strength and other physical properties that have impact on electrostatic swirl and the processing time.  There are mainly two kinds of pigments for rotomolding...

This article introduces several limitations of rotomolding technique in detail. 1. Large energy consumption. The mould must be repeatedly subjected to alternatively changing temperature during the rotomoling cycles, so in general, the rotomolding process need more energy than other related process....

This article introduces advantages of rotomolding fuel tanks in detail. 1. Light-weighted. When the engine power is the same, the lighter weight of car, the grater carrying capacity the car has. Therefore, designers tried best to lighten the car’s weight in order to save fuel. The relative density...

This article introduces features of rotomolding technique in detail. 1. The mold is simple and cost is low, which is suitable for manufacturing products with big size. The rotomolding mold needs to withstand high pressure and unnecessary for high intensity, so the structure is simple and easy to produce....

The quality of rotomolding mold determines the quality of rotomolding products, so it is important to maintain the mold. However, many workers don’t pay much attention to the maintenance of the mold in the process; they lack of relevant knowledge and thus cause the damage to the mold which is...

With the development of rotational molding technology, nowadays, rotomolding products have been widely used in daily life. Let’s look the following examples: 1. Containers This kind of products is widely used in different fields, such as water containers, liquid chemical (e.g. acids, alkali, salts,...

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,...
