Application of SICH-U Insulated Collective Hopper

Share to:

Collective hopper is usually mounted on molding machine, which ensures continuous supplying of plastic materials in production. As material supplying of feeding equipment is inconsistence, if there’s no such buffer for material, machine would experience out of material easily. Therefore, the collective hopper is widely used on the molding machine. Especially in applications of the central conveying system, materials will be remotely dried and far from the molding machine. However, the centralized conveying method would lead conveying suspension, so it is necessary to use the hopper.


Besides, plastic material would absorb moisture during production, transportation, and inventory. The moisture leads plastic materials to produce hydrolysis during the melting process, which would lower the mechanical performance of the plastic products and result in defective cosmetics. However, the defectiveness can’t be improved by parameter adjustment, so the plastic materials would usually be preheated. Meanwhile, in order to maintain the low moisture content of the material and save energy as much as possible, when materials get into the molding machine’s hopper, utilize some insulation devices can prevent they from heat lose. When materials suffer from heat lose, they contacted with the damp air which would cause re-absorption easily. For above reasons, Shini launches the SICH-U Insulated Collective Hopper series.

Shini SICH-U Insulated Collective Hopper is made of stainless steel, according to different capacities in6L,12L,24L, the storage part of the hopper adopts sandwich design, whose middle is filled with insulated cotton. When the temperature of plastic material in collective hopper is lower than160℃, and after 30 minutes the temperature decreases within30℃, which means the insulation is effective. At the same time, for easier opening of the collective hopper’s cover, we designed the hinge which makes the opening and cleaning more convenient.
