INTRODUCTION

The Seedling Tray Making Machine stands as a cornerstone solution for modern horticulture and agriculture, engineered as a specialized variant of our industry-leading multi-station Plastic Thermoforming Machine. Designed to address the core demands of large-scale plant propagation—high output, cost efficiency, and consistent quality—this equipment redefines automated production for seedling containers. By integrating advanced thermoforming technology into a fully automated system, it drastically reduces manual labor input while ensuring the stable, uniform output required for commercial nurseries, greenhouses, and agricultural cooperatives.
Built on the modular design of our Plastic Thermoforming Machine, the seedling tray-specific model is available in three-station and four-station configurations to match diverse production scales. The four-station version, equipped with a high-precision integrated punching station, delivers exceptional production efficiency and edge quality, eliminating the need for secondary trimming processes. This makes it ideal for mass manufacturing multi-cavity seedling trays, disposable plant pots, and custom horticultural containers—core products for the agricultural and horticultural supply chain.
Boasting remarkable material adaptability and speed performance, the machine processes PS, PP, and PET with seamless efficiency. For transparent PET trays, widely used for seedling cultivation with clear visibility, the maximum operating speed reaches 45 molds per minute. PP and PS, the most cost-effective materials for standard seedling trays, achieve a top speed of 30 molds per minute. A key operational note: production speed is adjusted based on product specifications—deep-draw plant pots or thick-sheet trays require extended forming times, a feature the machine’s intelligent system accommodates without compromising precision.
Powered by a next-generation control system and a forward-thinking design, the Seedling Tray Making Machine elevates operational reliability and quality control across every production cycle. Recognizing that seedling trays of varying sizes demand unique, fine-tuned parameters, we have embedded a dedicated parameter save function in the machine’s software. Once engineering teams optimize a specific mold for a given seedling size, the ideal production settings are permanently stored. When reusing the mold for subsequent runs, operators simply press “start,” and the machine automatically recalls and executes the validated parameters, enabling quick, error-free production resumption. For agricultural and horticultural businesses scaling up their propagation operations, this machine delivers unmatched efficiency and consistency.

PARTNER BARANDS

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
