05 — Key Advantages

Why Choose the 1600-Ton Sinter Hydraulic Press

The 1600-Ton Sinter Hydraulic Press delivers high thermal compression tonnage and multi-zone heating required for mass-producing biodegradable plant fiber trays. Its rapid steam-evacuation cycles, rigid platen alignment, and precise temperature regulation ensure high-strength food containers with minimal cycle times and zero warping.

Technical & Commercial Benefits

01

High Tonnage Thermoforming Compression Ensuring High Structural Strength

Delivering 1600 tons of continuous hydraulic force densely consolidates wet plant fibers into thin, rigid tray sidewalls. Sustained high compaction pressure during hot pressing ensures complete resin activation, preventing moisture absorption and sagging under load.

02

Precision Multi-Zone Heated Platens Delivering Uniform Heat Distribution

Integrated heating channels heat the upper core and lower cavity mold surfaces evenly across the entire working area. Uniform thermal exposure eliminates soft, under-cured spots and prevents localized tray scorching or warping during rapid drying cycles.

03

Multi-Stage Steam and Moisture Evacuation System Preventing Tray Blistering

The hydraulic system coordinates controlled micro-openings and vacuum-assisted venting to expel steam from wet pulp mats. Vapour release during hot pressing prevents internal blistering, surface delamination, and structural voids in finished food trays.

04

Ultra-Rigid Four-Column Frame Maintaining Precise Wall Parallelism

The heavy pre-stressed four-column frame absorbs high tonnage without flexing, holding platen alignment strictly parallel. Maintaining uniform daylight gap across multi-cavity dies ensures consistent wall thickness across complex compartment geometries.

05

Integrated Pneumatic Blow-Off and Hydraulic Stripping for Rapid Tray Release

An integrated 1000 kN bottom ejection mechanism works alongside air-assist blowers to gently release hot thermoformed trays. Synchronized mechanical lift prevents edge tearing and corner damage during high-speed automated robotic tray unloading.

06

Full Compliance with Global Eco-Packaging and Plastic Reduction Mandates

Thermoforming agricultural waste pulp directly replaces single-use plastics with fully compostable, food-grade containers. Producing non-toxic, heat-tolerant, and grease-resistant trays enables packaging manufacturers to meet strict global environmental regulations.
