Product Description

Plastic Fish Crate Mould – Engineered for Food, Beverage & Logistics

In the packaging industry, the Plastic Turnover Box (Crate Mould) is the backbone of efficient supply chains. From dairy farms and breweries to supermarkets and industrial warehouses, these containers must withstand extreme mechanical stress, temperature fluctuations, and constant circulation. The quality of your injection mold dictates the quality of every crate produced.

Technical Excellence: How We Build a Superior Crate Mould

1. Optimized Runner System: Hot Runner vs. Cold Runner

Most large turnover boxes require a 4 to 6-drop valve-gated hot runner system (e.g., HOTSET heating coils). We strategically select the system based on your production volume:

Feature	Hot Runner System (Recommended)	Cold Runner / 3-Plate Mold
Cycle Time	Shorter (No sprue cooling)	Longer
Automation	Fully automatic, no manual removal	Requires robot or manual gate removal
Material Waste	Zero (No runner scrap)	High (Regrind needed)
Part Quality	Better consistency, lower stress	Potential gate blemishes
Best For	High-volume (500k+ shots)	Prototyping or low volume

While hot runner molds have a higher initial investment, they eliminate regrind costs, reduce injection pressure, and allow for smaller injection machines—delivering a lower total cost per crate.

2. Precision Structure for Complex Ribs

Due to the large size and complex sidewall ribs of turnover boxes, our molds feature:

4-Side Hydraulic Sliders: Essential for forming perpendicular ribs and releasing the crate smoothly without scratching.

Stripper Plate Ejection: Provides uniform support during ejection, preventing deformation of large, thin-walled crates.

Balanced Gating: Larger runner diameters reduce shear heat and ensure the melt reaches all cavities evenly.

3. Material Selection & Durability

We match the steel to your production goals. For high-frequency production, we use DIN 1.2738 (718H) for cavities and DIN 1.2312 (P20) for cores, pre-hardened to ensure structural integrity.

Anti-Bending & Anti-Ageing: The mold design supports the use of HDPE with cross-hatched rib structures to maximize crate stiffness and impact resistance.

Temperature Control: Separate heated manifolds (insulated by standoff buttons) prevent heat transfer to the cooling circuits, ensuring the mold base remains cool while the melt stays hot.

Pre-Production Maintenance Checklist

To ensure longevity and stable production, we advise the following maintenance routine (which we also demonstrate during mold trial):

Surface Cleaning: Remove all anti-rust oil and check for residual debris.

Cooling Check: Verify water channels are clear of obstructions.

Mechanical Check: Confirm all guide pins, ejection pins, and sliders are lubricated and show no signs of wear.

Clamping: Ensure the mold plates are tightly secured to the injection machine platen.

Trial Run: Observe the opening/closing strokes and ejection sequence for any abnormalities before full-scale production.
