A Plastic Seeding Tray Mould (or Plant Tray Mould) is a precision tool used to create plastic trays for cultivating and transporting plants. Typically made from steel or aluminum, these Moulds are designed to form specific shapes and sizes via the injection Moulding process.
At Zhongyue Mould, we manufacture Moulds that produce trays with specific features like drainage holes and growth-enhancing root training ribs.

Why Upgrade to Injection Moulded Trays?
Many growers face a dilemma when switching from Styrofoam or thermoformed trays. We address the most common concerns below.
1. Maximizing Space & Profit: Cell Density
The Metric that Matters: Plants per square foot, not just cell count.
The Problem: A 144-cell tray performs very differently from a 128-cell 26"x13" tray.
Our Solution: Injection Moulded trays have thin, strong walls and no bulky outer rim, allowing for higher cell density without compromising plant quality.
2. Root Training Ribs: The Secret to Quality
What are they? Only premium vegetable trays feature this.
Why are they important? These ribs guide roots downward toward the drainage hole instead of letting them circle and choke.
Benefit: Healthier roots mean easier seedling removal, less labor, and stronger plants.
Calculating Your Return on Investment (ROI)
"Injection Moulded trays are more expensive upfront. How quickly will I earn my money back?"
It's a valid question. While Styrofoam trays seem cheaper, their short lifespan and high breakage cost you more over time.
Factor
Styrofoam/Thermoformed Trays
Injection Moulded Trays
Lifespan
1–2 Years (Prone to breaking)
5+ Years (Heavy-duty)
Cleaning
Difficult, requires harsh chemicals
Easy Steam Sterilization
Labor Cost
High (Difficult to extract plants)
Low (Smooth deMoulding)
ROI Timeline
Continuous Replacement Cost
< 1 Year to 5 Years
Our data shows that growers typically recoup their investment in under 5 years through reduced repurchase costs, higher survival rates, and lower labor expenses.
Addressing Sustainability & Hygiene Concerns
1. Disease Carry-Over Risk
The Problem: Styrofoam and thin thermoformed trays are porous and difficult to clean, harboring pathogens.
The Solution: Our injection Moulded trays are non-porous and smooth, allowing for effective sterilization with just water and steam. No nasty chemicals required.
2. Environmental Impact
Material Science: We manufacture trays using reprocessed and recyclable plastics.
Lifecycle: Instead of throwing away trays yearly (Styrofoam waste is a huge burden), our trays are built to last and be reprocessed again at the end of their life.
