Our Capabilities and Guarantee of Quality
Our integrated manufacturing process is the foundation of our quality promise. We control the process from the very beginning, utilizing our own sheet extrusion machines and sourcing premium raw materials from leading suppliers. This allows us to offer a wide selection of high-performance materials, including:
ABS, ASA, PC, HDPE, PMMA, and more.
Our technical team works closely with you to recommend the most suitable material based on your product's functional needs and application scenario, ensuring optimal performance and cost-effectiveness.
Cost-Effective Vacuum Forming Expertise
We excel in vacuum forming, a highly efficient manufacturing method that offers significant advantages for producing machine housings and covers:
Lower Costs: Compared to traditional injection molding, vacuum forming reduces production costs, especially for large parts and medium-volume runs, with lower tooling investment.
Design Flexibility & Customization: This process allows for the production of large, complex parts and offers extensive customization. We can utilize materials with specialized properties such as impact resistance, flame retardancy (UL94), and anti-static additives to extend the service life of your products.
Rapid Turnaround: From prototyping to full production, our one-stop service-from sheet extrusion to final packaging-ensures the fastest possible turnaround times without compromising on the quality and durability you expect.

1:Have you seen seedling trays that can hold a brick before without collapsing
2:The Extra Thick Black Plastic can withstand heavy loads.
3:Won't break or warp while moving trays filled with wet material
4:Store trays when not in use without worrying about being crushed
Our 72 Cell Plug trays have been recently upgraded to be 2.25" deep. This makes them the perfect tray for bottom watering your plants. Each cell will reach the bottom of your 1020 flat minimizing the amount of water needed.
The flat tray is a bit wider on the top and slightly tapers to the bottom to make the trays stackable for easy storage.
