PS food container/lunch box making machine mainly includes three machines as following: 1. Ps Foam Sheet Extrusion Machine------- Make the sheet for forming part. 2. PS Foaming machine--------------------- Make different type of product with the forming mold,cutting mold etc. 3. PS recycling machine-------------------- Recycled the wasted material to PS granule again as the raw material.
1. PS Foam Sheet Extrusion Machine
.It adopts Gentian type double-stage series high foam technology.
.This equipment adopts high speed hydraulic filter changer, which has steady feature, can change the filter immediately without stopping the machine.
The raw material is general polystyrene granule (GPPS).
In the extruding process, foam agent (such as butane gas or LPG) is injected at high pressure.
After extruding, foaming, cooling, shaping and hauling off, it is winding to finished ps foam sheet rolls.
After vacuum forming system, the finished PS foaming sheet can be made into variety of packaging vessels ,such as fast food box ,aquatic plate,supermarket tray ,cake tray , KT board ,instant noodle bowl ,foam tray etc.
It is widely used in the packing for food, fruit, and advertising industrial products, etc.
2. PS Foaming machine
It is an all-powerful thermal forming machine with integration of vacuum forming and cutting.
It adopts remote infrared ceramic heater in heating zone, with which the machine get the most stable and even temperature.
It adopts temperature digital system, which is convenient for the workers to know the temperature of each heating zone quickly. Also it is easily operate and make more efficiency.
It adopts Japanese servo motor & drive, Mitsubishi PLC mechanical and electronic integration control, touch screen for operating.
It features reliable stability, large forming area and fast speed,as well as highly degree of automation & economic on manpower.
It adopts automatic pneumatic device in feeding area, which reduces the labor force.
3. PS recycling machine
It adopts fully automatic temperature controlling, one manual filter changer device at the front of the machine to filtrate the impurity of the recycling material.
the die head made by special alloy steel, follow one set of electric heater bands and automatic temperature controller,die head passageway is designed special, the press of granule formed need can be ensured.
water channel adopts corrosion resistant plate, cooling water circulation, ensure the material line cooled blance and sufficient.
granulator cutter adopts frequency speed control of motor drive, the speed of hauling off controlled accurate, the length of granule equality.
It is the ideal equipment to recycle the plastic scrap .It features compact structure and easy operation.
It can process pe/ps/pp material and is mainly used to recycle the high foam polystyrene and high foam polystyrene products.
