Thickness Gauge

Function

Non-contact capacitive sensors designed for in-line film thickness measurement, which measure thickness in-line without scratching the film surface, are especially suitable for the production of more viscous and surface-sensitive films.

Advantage

The probe has two sensors that work in parallel to produce separate capacitances. This combination allows the thickness to be calculated regardless of the distance. It does not affect the results in the case of continuously changing air gaps (ranging from 100 to 350um).

Horizontal upward rotating traction device

Function

Horizontal rotary traction adopts horizontal ±360°swinging rotation, with constant film linear speed, scientific and reasonable structure, energy-saving and easy maintenance. It replaces the rotary die head, simplifies the die head structure, and completely solves a series of problems such as long rotary die head runners, difficult melt sealing, easy material leakage, uneven heating, difficult maintenance, and large film tolerance. At the same time, it simplifies the difficulty of formulating materials and controlling production process for multi-layer co-extruded products. If combined with the film bubble internal cooling system, it can produce film products with higher transparency and better physical properties.

Advantage

The film produced by using this device has extraordinary flatness and precise cylindricity of the film roll, so that the film thickness deviation triggered by the die head, wind ring and tower is evenly distributed on the film roll, which ensures high quality of film roll forming in the winder and meets the requirements of high precision and high speed printing lamination.

Mold head

Function

Through continuous technological innovation, Pepperard has created a wide range of high performance die heads, such as, center feed dies, side feed dies, and flat stack dies. With very short solute flow paths, different resins are processed to obtain perfect film products.

Advantage

Each group adopts independent PLC operation. Improve the computing power and execution speed.

Direct communication between each group of hoppers and the film blower. Improved data transfer accuracy.

The operating system is integrated with the film blower. User-friendly operation.

Centralized winding system

Function

It adopts the center of the reel to wind up, plus the taper control of the system to calculate the winding diameter in real time. It can overcome the problem of equal tension due to different roll diameters. Finally, it can achieve the purpose of tightening the product inside and loosening it outside, so that the film roll will not be deformed.
