Injection molding operations generating 50-120 kg/h of production scrap need a crusher that keeps pace with the molding machine cycle. The ZL-PC300 Injection Molding Scrap Crusher delivers 220-300 kg/h throughput with in-line integration capability, automatic start/stop control, and color separation support for high-volume production environments.

Injection molding operations generate three scrap types with distinct characteristics: sprues (cylindrical channels, 2-8 mm diameter, 20-100 mm length), runners (branching distribution channels, 5-15 mm diameter), off-spec parts (full finished parts with defects, 50-500 g each). Scrap ratios by weight: sprues 10-20%, runners 5-15%, off-spec 2-5% of finished part weight.
For a molding operation producing 1,000 kg/day of finished parts, total scrap generation is 170-400 kg/day. The ZL-PC300's 220-300 kg/h peak throughput processes the daily scrap in 1-2 hours, leaving 6-7 hours of throughput reserve for expanded production or second-shift operation.
Injection molding operations pursuing closed-loop scrap recycling recover 90% of production scrap as reusable flake. The ZL-PC300 produces 8 mm screen flake suitable for direct re-injection after color verification. Each closed-loop cycle reduces polymer molecular weight by 2-5% (measured as Melt Flow Index increase).
For molding operations running 100% closed-loop production scrap, the typical cycle count is 4-6 before molecular weight degradation requires blending with 30-50% virgin resin. The ZL-PC300's sharp SKD-11 blades cut cleanly without thermal degradation, preserving molecular weight and impact strength across the 4-6 cycle range.
For molding operations with robotic sprue pickers, the ZL-PC300 integrates directly with the robot arm output. The robot picks sprues and runners from the mold and drops them into the ZL-PC300 feed chute. The crusher's start signal can be triggered by the robot cycle completion, ensuring synchronized operation.
For high-volume molding operations with 4-6 second cycle times, the ZL-PC300 keeps pace with the molding machine throughput without operator intervention. The crusher's 220 kg/h capacity supports 4-6 medium-sized injection molding machines (100-300 ton clamping force) operating in parallel.
The ZL-PC300 processes 4 common injection molding polymers: PP (polypropylene) at 280-300 kg/h, ABS (acrylonitrile butadiene styrene) at 250-280 kg/h, PC (polycarbonate) at 220-250 kg/h, POM (acetal) at 200-220 kg/h. The throughput differential reflects material hardness and density.
For molding operations running multiple polymer types, the ZL-PC300's 12-blade rotor handles the variability without screen change. Color separation is recommended for multi-polymer operations to prevent cross-contamination of recycled flake.
Glass-fiber reinforced polymers (GF-PP, GF-ABS, GF-PA66) require special handling due to abrasive wear on blades. The ZL-PC300's standard SKD-11 blades process GF materials at 30-40% reduced throughput with 50% reduced blade life. For high-volume GF processing, the optional carbide-tipped blade upgrade (USD 480) extends blade life to 2,400-3,600 hours.
For molding operations producing GF-reinforced parts (automotive, appliance, electronics), the ZL-PC300 with carbide blades supports closed-loop recycling of the high-value GF materials. The carbide blade upgrade pays back in 3-6 months for operations processing 500+ kg/day of GF materials.
Molding operations producing parts in multiple colors require scrap separation to maintain color purity. The ZL-PC300 supports 3 separation strategies: 1) upstream manual separation (operator separates by color before crushing), 2) post-crush color sorting (NIR sorter downstream), 3) batch processing (crush one color at a time, clean crusher between batches).
For molding operations running 3-5 colors, batch processing with the ZL-PC300 is the cost-effective approach. The 30-minute color changeover (crusher cleaning + screen cleaning) is acceptable for production runs of 4+ hours per color. For high-color-mix operations (>10 colors/day), upstream separation or post-crush NIR sorting is more efficient.
Q: How is the ZL-PC300 integrated with injection molding machines?
Standard integration: takeaway conveyor (3-meter, USD 480) connects the shredder feed opening to the molding machine discharge chute. Robot integration: sprue picker drops directly into crusher feed. Both methods process 50-100 kg/h per molding machine.
Q: What is the maximum throughput per molding machine?
Typically 80-120 kg/h per injection molding machine for sprue and runner scrap. For larger machines (500+ ton clamping force), throughput can reach 150-200 kg/h. The ZL-PC300 capacity (300 kg/h) supports 3-4 injection molding machines per crusher.
Q: Can the ZL-PC300 process glass-fiber-reinforced materials?
Yes, at 30-40% reduced throughput with standard SKD-11 blades. For high-volume GF processing, the optional carbide-tipped blade upgrade (USD 480) extends blade life by 3-4x. The carbide upgrade pays back in 3-6 months for operations processing 500+ kg/day of GF materials.
Q: What is the difference between in-line and batch processing?
In-line processing: shredder integrated with the molding machine, processing scrap as it is generated. Higher capital cost (conveyor integration) but lower labor cost and higher material value (less contamination). Batch processing: scrap collected and shredded periodically. Lower capital cost but requires labor for collection and loses some material value due to contamination during collection.
Q: How does the ZL-PC300 handle different colors without cross-contamination?
Batch processing with color changeover (30 minutes for crusher cleaning) is the cost-effective approach for 3-5 color operations. For high-color-mix operations, upstream separation or post-crush NIR sorting is recommended.
