The laboratory tablet press developed and manufactured by Zhongcheng is suitable for various rubber raw materials, plastic granules such as PP, PE, PVC, ABS, pigments, oils, and chemical raw materials, enabling the hot pressing and molding of materials.

Here's an introduction to its features:

Guides: Four high-intensity precision guides support the upper and lower double-layer mold plate locking structure. The machine frame is designed with heavy-duty steel, effectively reducing deformation and damage. The parallelism between mold plates is high, the load is stable, and they are sturdy and durable, capable of meeting high-precision pressing requirements.

Molded Plate: Made of SKD chromium molybdenum alloy, the surface is treated with carburization, chrome plating, and polishing, achieving a Rockwell hardness of up to 60HRC, ensuring durability and resistance to rust. It is divided into a standard upper heating zone and a lower cooling zone, with the upper heating plate featuring multiple rows of electric heating tubes for stable and reliable heating. The lower cooling plate is equipped with a serpentine water cooling pipeline for rapid and powerful temperature reduction. The integrated electric heating and water cooling design is widely applicable. It boasts fast heat transfer, corrosion resistance, high hardness, and no deformation. The back features an internal heater and temperature sensor, offering high power, quick temperature rise, sensitive temperature measurement, even heating, and a small temperature error range.

The Proportional Pressure Flow Compound Valve Control System features adjustable pressure, automatic pressure compensation, and delayed shutdown with pressure retention. This hydraulic system comes with a dual-speed operating mode, utilizing high-approach speed at low pressure and low-approach speed at high pressure. Multiple exhaust cycles can be set, ensuring the mold pressure reaches saturation.

The electrical control system is supplied in accordance with CE or higher standards, featuring genuine brand electrical components. Temperature, time, and pressure can be set and displayed. The molding action operates in both manual and automatic modes, offering convenient, accurate, and reliable operation.

The hydraulic system features delayed shutdown and pressure retention capabilities, including at least two adjustable pressure segments and two unit display options. Multiple exhaust actions can be set at will. The optimized electro-hydraulic drive combination design enhances efficiency while reducing the product's energy consumption, achieving energy-saving and high-efficiency performance.
