The mold thickness adjustment mechanism should regularly check whether the large gear or chain of the drive shaft is offset or slack. Whether the screw of the pressure plate on the gear is loose, whether the lubricating grease is enough, etc.

Oil pressure part

In the hydraulic system, attention should be paid to the cleanliness of the hydraulic oil to maintain the quality of the hydraulic oil. The stable and high-quality hydraulic oil should be used. In addition to regular replacement, its working temperature should be properly controlled below 50C to avoid deterioration. And affect the stability of hydraulic action.
When the injection molding machine is in operation, if there is any abnormality in the system, the controller will sound an alarm, and a line of warning messages will appear at the bottom of the camp screen.

How Does A Thermoforming Machine Work

Material preparation: The thermoforming machine is set up by loading the appropriate plastic sheet material onto the machine. The plastic sheet can be in roll form or pre-cut sheets, depending on the machine design and requirements.

Heating the plastic sheet: The thermoforming machine has a heating zone where the plastic sheet is heated to its softening point. Various heating methods such as radiant heat, convection heat, or infrared heating elements are employed to heat the plastic sheet evenly and uniformly.

Indexing or feeding the plastic sheet: Once the plastic sheet is heated to the desired temperature, it is advanced or indexed into the forming station of the machine. This can be achieved through mechanical or automated feeding mechanisms that ensure precise positioning of the plastic sheet.

Forming the plastic sheet: In the forming station, the heated plastic sheet is brought into contact with a mold or set of molds. The molds define the shape and contour of the final product. Depending on the type of thermoforming machine, the forming process may involve vacuum forming, pressure forming, or other techniques.

Applying vacuum or pressure: In vacuum forming, a vacuum is applied to draw the heated plastic sheet onto the mold cavity, conforming it to the desired shape. In pressure forming, in addition to the vacuum, air pressure is also applied to help shape the plastic sheet.

Cooling the formed product: After the forming process, the formed plastic product needs to be cooled to solidify and retain its shape. Cooling can be achieved through a combination of air cooling, water cooling, or contact with cooled surfaces, depending on the machine configuration.

Trimming and finishing: Once the formed plastic product is cooled and solidified, any excess material or flash is trimmed or cut away. This can be done manually or using automated trimming mechanisms integrated into the thermoforming machine. Additional finishing operations such as hole punching, embossing, or edge trimming may also be performed as required.

Product removal and handling: The finished thermoformed products are then removed from the machine, either manually or using automation, and are ready for further processing, packaging, or assembly.
