PS foam thermoforming machine is a kind of equipment specially used for producing PS foam products. PS (polystyrene) foam is usually used in food packaging, beverage containers, household appliance packaging and other fields, with good heat insulation, cushioning, light weight and low cost.
Working principle of PS foam thermoforming machine:
1. Heating: First, heat the PS foam sheet to an appropriate temperature to soften its surface and make it plastic.
2. Molding: Put the softened foam sheet into the mold, and make the foam material fit the shape of the mold tightly through vacuum, pressure or mechanical pressure to complete the molding.
3. Cooling: The molded product is cooled and solidified to maintain its molded state.
4. Demolding and trimming: The cooled product is taken out of the mold, trimmed and cleaned to ensure that the size and appearance meet the requirements.
The choice of this equipment usually depends on the production scale, the complexity of the product and the required production efficiency.
