Cooling Tower Filling Vacuum Forming Machine

Cooling Tower Filling Vacuum Forming Machine (also known as vacuum molding machine, blister forming machine or Thermoforming machine ), we are one of the best vacuum forming machine manufactures in China

Intro

The PVC material is heated by three stages upper and lower infrared heating furnace, and the temperature of each segment is adjustable. The lower furnace is equipped with Teflon cloth as a supporting device for sagging material. Adjusting the temperature, make sure the PVC material won’t be completely softened and drooping , moving the sheet to the molding station by servo motor, then the pressurizing system started, the upper mold and lower mold will match with each other perfectly. Then the positive and negative pressure forming process would be realized.

It’s a idea machine for thermoforming and auto-cutting of cooling tower filling material

Technical process

The production process of the cooling tower filler vacuum forming machine mainly includes the following steps:

Sheet preparation: Place the plastic sheet on the material rack of the machine to ensure that the flatness and size of the sheet meet the requirements.
Heating and softening: Heat the plastic sheet through a heating device (such as a heating plate or oven) to soften it to a suitable temperature for subsequent molding operations. The heating temperature and time are adjusted according to the type and thickness of the plastic to ensure that the sheet can be heated evenly and reach the required degree of softening.
Vacuum adsorption: When the sheet softens, the vacuum forming machine starts the vacuum system to generate negative pressure on the mold surface. The softened sheet is adsorbed to the mold surface under the action of atmospheric pressure and fits the shape of the mold tightly.
Cooling and shaping: After the sheet is adsorbed on the mold, it is quickly cooled by a cooling device (such as a cooling fan or cooling water channel) to solidify the plastic and maintain the shape given by the mold.
Demolding and removal: After cooling is completed, the vacuum adsorption is released and the molded plastic product is removed from the mold.
Subsequent processing: It may include trimming, deburring and other subsequent processing of the product to obtain the final product.

In the whole production process, the design and manufacture of molds are very critical, which determines the shape and dimensional accuracy of the product. In addition, operators need to accurately control parameters such as heating temperature, vacuum degree, cooling time, etc. according to different plastic materials and product requirements to ensure the production of qualified products.

The equipment is customized for customers in the US, is specially used for cooling tower filling material thermoforming and automatic cutting.Sheet pulling, heating, forming, cutting, stacking and scrap recycling is finished in one machine, which reduces manual labor, operation easily, improves production efficiency, it has high reliability and fully automation.
