ECS130 PE LDPE HDPE LLDPE Film Pelletizing Machine

The ECS130 PE/LDPE/HDPE/LLDPE film pelletizing machine is a compact, high-efficiency recycling line designed to convert clean post-industrial or post-consumer plastic films into uniform pellets. Featuring a single-screw extruder, hydraulic screen changer, and die-face underwater cutting system, it ensures stable output and excellent pellet quality. Ideal for processing shopping bags, shrink wrap, agricultural film, and packaging scraps, the ECS130 delivers reliable performance with low energy consumption—perfect for small to medium-scale recyclers worldwide.

HDPE Plastic Pelletizing Machine

The HDPE plastic pelletizing machine is designed to convert clean HDPE flakes—sourced from bottles, drums, pipes, or film—into high-quality, uniform pellets. Featuring a robust single-screw extruder, precision die head, and automatic underwater or strand-cutting system, it ensures consistent melt homogeneity and pellet integrity. The resulting pellets are ideal for reuse in injection molding, blow molding, and pipe extrusion. Built with energy-efficient motors and PLC control, the machine offers stable, low-maintenance operation for recycling plants and compounders worldwide.

Underwater Pelletizer Machine for Thermoplastics Elastomer

The underwater pelletizer machine for thermoplastic elastomers (TPE/TPR/TPV) is a high-precision system that cuts molten polymer strands directly underwater into uniform, spherical pellets. Designed for heat-sensitive and sticky materials, it ensures excellent surface finish, minimal dust, and consistent particle size. Integrated with a melt pump and die plate, the system offers stable pressure and high throughput—ideal for producing premium-grade TPE pellets used in automotive, medical, and consumer goods applications.

Frequently Asked Questions

Can the machine process mixed plastic materials?

Yes. Twin-screw plastic pelletizing machine is specially designed for mixed plastic materials; it can uniformly mix and melt different types of plastics. For materials with large differences in properties, a pre-mixing module can be added to ensure pellet quality.

What is the daily maintenance requirement?

Daily maintenance mainly includes: 1) Clean the feeding hopper and filter screen regularly to avoid impurity accumulation; 2) Check the wear of the screw and cutter, and replace them in time if there is excessive wear; 3) Lubricate the transmission parts (bearing, gearbox) regularly; 4) Check the heating system and temperature sensor to ensure accurate temperature control.

Is it necessary to dry the plastic materials before feeding?

Yes. It is recommended to dry the plastic materials (especially recycled plastic flakes) to a moisture content of ≤1% before feeding. Excessive moisture will cause bubbles in the pellets, affecting product quality. We can configure a pre-drying module according to customer needs.

What is the delivery time and payment terms?

The delivery time for standard models is 20-30 days; customized models take 35-45 days. We support flexible payment terms (T/T, L/C, DP) and accept small-batch trial orders. For bulk orders, we provide preferential pricing and phased delivery services.

Do you provide sample testing services?

Yes. Customers can send their plastic material samples to us, and we will use our pelletizing machine to process them into finished pellets and send the samples back for inspection. We also provide test reports (pellet size, moisture content, purity) to help customers confirm the equipment’s performance. The courier cost is borne by the customer.
