INTRODUCTION

The Injection Tray Thermoforming Machine represents a significant advancement in specialized manufacturing, leveraging the core technology of the Plastic Thermoforming Machine to deliver high-precision, high-volume production of injection trays for medical, pharmaceutical, and industrial applications. Developed to meet the strict quality and efficiency demands of modern packaging industries, this machine combines automation, precision, and flexibility to provide a superior production solution.
These highly automated Injection Tray Thermoforming Machine systems, based on Plastic Thermoforming Machine technology, are typically offered in three-station and four-station configurations. The four-station model, featuring an integrated punching station, provides exceptional efficiency and cutting precision—critical for producing injection trays with clean edges and accurate dimensions, which are essential for medical packaging compliance. Beyond injection trays, this versatile machine can also manufacture other disposable products, including syringe trays, blister packs, cup lids, and general plastic packaging, making it a multi-functional asset for manufacturers.

In terms of performance, the Injection Tray Thermoforming Machine boasts impressive speed and material flexibility. It is fully capable of processing medical-grade PET, PP, and PS sheets, which are widely used in injection tray production. When using clear PET sheets—preferred for their transparency and ability to showcase medical products—the machine can operate at a maximum speed of 45 molds per minute. For PP sheets, which offer excellent durability and heat resistance, the maximum speed is around 30 molds per minute. Actual operating speed is dependent on injection tray design complexity, depth, and plastic sheet thickness, with more complex trays requiring additional forming time.

Adopting a new-generation design concept and a future-oriented control system, the Injection Tray Thermoforming Machine ensures stable operation and easy validation. To address the need for consistent quality across different injection tray molds, the machine includes a parameter save function. Once engineers debug and optimize the operating parameters for a specific mold, these settings are permanently stored. When the same mold is used again, the machine automatically applies the saved parameters, eliminating the need for repeated debugging, reducing labor costs, and ensuring consistent, high-quality output.

Proximity switch clever control, getting the rid of falling down of the sheet by conveying too fast.

Double stations, big diameter, reduce the frequency of changing sheet coil, improve the the production efficiency.

Max undertake roll of sheet

Weight:600kg, Diameter 800mm.

Feeding sheet part

Automatic feeding reduces human resource costs.

Actively transport the sheet and reduce the load on the conveying servo motor.

Cleverly control the proximity switch to prevent the sheet from falling too quickly during transportation.

Human-machine interface

Controlled by microcomputer and programmable controller (PLC), all action programs can be operated through the human-machine interface, simple and convenient, 15-inch touch screen.

Heater

1. Vacuum insulation cotton is installed in the heater, which has a fast reaction speed, short processing time and energy saving.

2. The furnace body is divided into two layers, the layout of the heating tiles is optimized, so that the plate is heated evenly.

Molding station

1. Mold changing auxiliary mechanism, using sliding guide rails and support rods to achieve fast mold change, saving time and effort.

2. Adopting high-power servo motor drive, high precision, high efficiency and low noise.

Molding mold

The working principle is a combination of positive and negative pressure, and some nylon plugs are used to assist stretching in the mold to make it have stronger molding ability.

There is cooling water in the mold cavity to speed up the cooling speed and make demolding easier.

Guide head structure

The workstation is supported by four columns (45# steel, hard chrome plated).

The integrated mold table (QT-600 steel) is made by a high-precision CNC milling machine. Therefore, it is wear-resistant, stable, and accurate, which prolongs the service life of the equipment.
