How To Make Good Quality 120L Bin Mould?
1. Designing the mould: Start by creating a detailed design of the 120L bin mould. Consider factors such as the size and shape of the bin, as well as any additional features like handles or wheels. The design should be precise and tailored to meet the specific requirements of the bin.
2. Selecting the right materials: Choose high-quality materials for the mould that are durable and can withstand the pressure and temperature requirements of the moulding process. Consider materials like steel for the mould base and inserts to ensure longevity.

Plastic Material (Bin Quality)
HDPE (Recommended) – Superior impact & UV resistance.
PP (Alternative) – Lighter but less rigid.
3.Precision engineering: Use advanced machining techniques to create intricate details and smooth finishes.
CNC Milling & EDM
CNC machining for core/cavity shaping.
EDM (Electrical Discharge Machining) for fine details (logos, textures).
Polishing & Texture
Mirror polish for smooth ejection.
Grit-blasted finish for matte aesthetics.
4. Proper cooling and ventilation: To ensure the plastic bin moulding process goes smoothly, it is essential to have proper cooling and ventilation systems in place. This will help prevent warping and defects in the final product.
5. Testing and troubleshooting: Before mass producing the bins, test the mould to ensure it produces bins of the desired quality. Make any necessary adjustments or repairs as needed to ensure consistent results.
By following these steps and paying attention to detail, you can create a good quality 120L bin mould that will produce durable and efficient bins for years to come. Remember to continuously monitor and maintain the mould to ensure optimal performance.

Mould Maintenance Tips
1. Regular Cleaning
After Each Production Run:
Remove plastic residues (especially for materials like HDPE/PP) using non-abrasive solvents or ultrasonic cleaning.
Avoid metal scrapers that can damage the mold surface.
Vent Cleaning: Clear clogged vents to prevent gas traps and burn marks on parts.
2. Lubrication & Corrosion Prevention
Moving Parts: Apply high-temperature grease to ejector pins, guide rails, and sliders weekly.
Storage:
Coat the mold with anti-rust oil if idle for >1 week.
Store in a dry, temperature-controlled environment.
3. Cooling System Maintenance
Monthly Flushing: Remove mineral deposits in cooling channels with descaling agents.
Leak Tests: Check for water leaks that could cause corrosion or uneven cooling.
4. Proper Handling & Storage
Apply rust inhibitor (e.g., VCI paper or anti-corrosion spray).
Store in a dry, temperature-controlled environment (humidity <60%).
Cover with protective film to prevent dust accumulation..
Package &. Delivery
1.Before the bin mould is shipped, we will check whether the opening and closing of the mould is smooth, the water cooling system,the hydraulic oil system and the hot runner system.
2. The cavity and core are cleaned without iron filings and impurities.
3. Blow the waterway clean to prevent long-term sea transportation from rusting.
4. We spray anti-rust agent on the inside of the mold, spray paint on the outside of the mould, and apply anti -rust oil on the thimble.
5. We will put a nameplate on the mold, it shows the mould name, the year of production and mould information, mould weight and size.
6: Mould parts are provided free of charge (convenient for customers to replace).

How to do 120L Bin Mould Order Processing?
|
Step 1: Define Your Requirements >Before contacting a mold manufacturer, clarify: >Bin Design (3D model or drawings – .STEP/x_t format preferred). >Material (HDPE, PP, recycled plastic?). >Production Volume (low/high volume – affects mould steel choice). >Mould Lifespan (50,000 shot). >Hot runner vs. cold runner system? >Surface Finish (smooth, textured, grain pattern?). >Additional Features (handles, wheels, logos, stackability). Step2: Request Quotes & Compare Offers Provide: >3D files or technical drawings. (If don't have design, please send sample photos with size information.) >Material type, expected cycle time, and cavitation (single/multi-cavity). Step 3: Finalize Mold Design (DFM Review) Our company will provide: >DFM Report (Design for Manufacturability – checks draft angles, wall thickness, ejection, etc.). >Mold Flow Analysis (simulates plastic filling to prevent defects). >Approval of 3D mould design before machining. Step 4: Bin Mould Manufacturing &. QC Checks Stages: >Machining (CNC, EDM, polishing). >Trial shots (test moulds with actual plastic). >Adjustments (fine-tuning for defects like warpage or sink marks). >Final inspection (dimension checks, surface quality). Step 5: Mold Delivery & Production Start Shipping: >FOB (you arrange freight) or CIF >Ensure proper packaging to prevent damage. Production: >Conduct initial production runs to verify consistency. >Optimize cycle time and cooling system for efficiency.
