Types of Complete Plastic Production Equipment Sets

Complete sets of plastic production equipment are primarily categorized-based on processing techniques-into four major groups: plastic compounding, plastic molding, secondary plastic processing, and auxiliary machinery. Among these, molding machinery constitutes the core component, accounting for over 80% of the industry's total output value. Currently, the most prevalent equipment combinations on the market typically revolve around three key processes: injection molding, extrusion molding, and blow molding-each corresponding to the specific requirements of different end products.

Core Molding Equipment Sets

This represents the most critical stage in plastic processing, as it directly determines the physical form of the final product.

Injection Molding Equipment Sets

Primarily used for manufacturing plastic products with complex shapes and precise dimensions (such as appliance housings, automotive components, and daily necessities). A complete production line typically comprises an injection molding machine (the main unit), an automatic feeding system, a mold temperature controller, a robotic arm for part extraction, and a subsequent crushing and recycling system. Injection molding machines account for over 40% of the total output value, making them the dominant product within the plastic machinery sector.

Extrusion Molding Equipment Sets

Suitable for producing continuous profiles, such as pipes, sheets, films, wires, and cables. In this equipment set, the extruder serves as the main unit; it must be paired with precision dies (die heads), sizing and cooling devices, haul-offs, cutters, and winders to form a complete production line. For instance, the production of PVC pipes requires a conical twin-screw extruder combined with a vacuum sizing tank and a planetary cutter.

Blow Molding Equipment Sets

Specifically designed for manufacturing hollow containers, such as beverage bottles, oil drums, and chemical storage barrels. The complete equipment set includes an extrusion blow molding machine or an injection blow molding machine, parison control devices, blow molds, and post-processing trimming equipment. Large-scale hollow blow molding machines (such as those used to produce beer kegs) are typically equipped with accumulator-type die heads and multi-layer co-extrusion die heads.
