PET (polyethylene terephthalate)

It has high density and strong hygroscopicity, requiring dehumidification and drying prior to processing; the flowability of pellets and bottle flakes is highly sensitive to temperature changes.

PP (polypropylene)

Lightweight, heat-resistant, and easily crystallizable, it can be used to manufacture injection-molded parts, nonwoven fabrics, food containers, sheets, and corrugated pipes.

PE (polyethylene, collectively referring to HDPE, LDPE, and LLDPE)

It is resistant to low temperatures and to acids and alkalis, with excellent chemical stability.

LDPE (low-density polyethylene)

It has a soft texture, excellent toughness, and good melt flow, and is commonly used for films, flexible packaging, hoses, and coating materials.

HDPE (High-Density Polyethylene)

It features excellent rigidity, impact resistance, and high crystallinity, with relatively poor flowability, making it suitable for pipes, drums, reusable crates, and blow-molded products.

Servo Motor Retrofitting

The all-new servo‑hydraulic system employs liquid‑cooled servo motors, liquid‑cooled drives, and a dedicated cooling system, ensuring optimal operating temperatures and enhanced energy efficiency. Additionally, liquid‑cooled motors are 20–40% shorter than air‑cooled counterparts, and their lower moment of inertia reduces energy consumption during acceleration and deceleration.

Energy-saving, noise reduction, and stable operation

Energy Efficiency: The servo‑hydraulic control system employs a closed loop formed by pressure sensors and encoders, enabling precise regulation of hydraulic system pressure and flow to deliver power only when needed. Compared with conventional hydraulic systems, this approach significantly reduces wasted energy. Noise Reduction: By utilizing a servo‑driven gear pump, noise levels are lower than those of traditional oil pumps. Moreover, under low‑pressure, low‑flow conditions, the servo control system operates at reduced speeds or even remains stationary, thereby minimizing continuous noise generation. Stability: Servo systems are optimized to operate at their ideal temperature; however, as operating temperatures rise, thermal degradation may occur.

Energy-saving retrofit of heating coils

The new energy‑saving heating coil technology differs from conventional heaters that rely solely on conduction or infrared radiation. It features a unique structural design that not only provides a conductive pathway for heat transfer but also incorporates reflective elements to enhance infrared radiation, combining both infrared radiation and thermal conduction into a single system. Additionally, it integrates mirror‑like reflection with a high‑efficiency nano‑insulation layer, delivering dual‑mode thermal insulation.

Energy-saving and convenient • Safe and accurate • Precisely tailored

Energy Efficiency: Achieves energy savings of 20% or more, with a high return on investment. Convenience: Requires no modifications to the injection molding machine; the surface temperature of the barrel guard remains below 70°C. Safety: Reduces the surface temperature of the guard, preventing burns, improving the workshop environment, and complying with national safety standards. Precision: Prevents overheating, maintains low heating-element surface temperatures, minimizes temperature gradients, offers lightweight thermal insulation, and is compatible with a wide range of materials. Compatibility: Fits injection molding machines of all brands and models, is easy to install, and features an aesthetically pleasing design.
