INTRODUCTION

In the competitive horticultural market, custom seedling trays and plant pots are essential for specialized cultivation—from vegetable seedlings to ornamental flowers—and our Seedling Tray Making Machine is purpose-built to meet this demand. As a precision-focused iteration of our multi-station Plastic Thermoforming Machine, it combines ultra-high dimensional accuracy with automated production, ensuring every tray and pot meets the strict specifications of commercial nurseries and home gardeners alike. Unlike standard thermoforming equipment, this machine is engineered to handle both standard mass production and small-batch custom orders, making it a versatile asset for horticultural manufacturers.
The system’s modular three-station and four-station designs form the backbone of its flexibility. The four-station configuration, featuring an integrated precision punching unit, ensures clean, burr-free edges on custom seedling trays and deep-draw plant pots—critical for healthy root development and easy transplanting. This integration streamlines the production workflow, reducing material waste and production time compared to standalone thermoforming and trimming setups. The Seedling Tray Making Machine is fully capable of manufacturing a diverse range of horticultural products, including multi-cell propagation trays, round/ square plant pots, and specialized seedling containers for commercial greenhouse operations.
Performance and material versatility are hallmarks of this machine. It excels at processing PS, PP, and PET, with speed tailored to material and product type: PET (for clear, durable trays) reaches 45 molds per minute, while PP and PS (for cost-effective, lightweight containers) hit 30 molds per minute. For custom designs—such as deep-dive pots or irregularly shaped seedling trays—forming time is extended to maintain precision, a capability the machine’s adaptive control system manages seamlessly. This balance of speed, flexibility, and accuracy makes it suitable for both high-volume commercial runs and low-volume custom production.
At the core of the Seedling Tray Making Machine is a future-ready control system with a specialized parameter storage function. Each custom mold, whether for a specific seedling size or unique pot design, has its optimized operating parameters permanently saved in the system. After initial debugging and validation by our engineering team, these settings are instantly accessible for future production runs. Operators can restart production with a single click, eliminating time-consuming re-calibration and minimizing human error. For horticultural manufacturers seeking a Plastic Thermoforming Machine that adapts to both mass and custom production needs, this machine delivers unrivaled precision and efficiency.

ESSENTIAL COMPONENT

Loading sheet part

Load automatically, lower human resource cost.

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.

A five-point-connecting-rod structure
