Plastic Garbage Bin Mould
SINOMOULD has over 20 years of experience in the environmental protection plastic products industry, specializing in the development and manufacturing of plastic garbage bin moulds and sorted garbage bin moulds. We provide stable, high-strength, long-life and reliable mould solutions for environmental equipment manufacturers, municipal supporting enterprises and daily plastic product manufacturers.
For garbage bins of different volumes, structures, flip-top, pedal-controlled or wheeled styles, SINOMOULD offers not only standalone moulds for bin body, lid or pedal mechanism, but also combined mould solutions capable of producing both body and lid in one mould. This ensures precise fitting and structural stability while greatly improving efficiency and reducing overall investment.
In addition, SINOMOULD supplies fully automated garbage bin production line solutions. By integrating robotic take-out systems after injection moulding, products are handled smoothly without manual contact, greatly improving consistency and stability—ideal for high-volume, high-standard production of municipal and sorted garbage bins.

Key Quality Points of Plastic Garbage Bin Moulds
- Structural Strength & Dimensional Stability
Precise control of wall thickness uniformity, reinforcing rib moulding, rim and wheel shaft accuracy ensures high compression, impact and aging resistance for long-term outdoor use.
- Appearance & Surface Quality
Mould cavities with high gloss or uniform texture minimize weld lines, sink marks and bubbles, ensuring smooth appearance and consistent color.
- Multi-Cavity Balance & Weight Consistency
Optimized runner balance and gate layout ensure consistent weight, size and wall thickness across all cavities for stable mass production.
- Long-Term Stability & Wear Resistance
Key stressed parts use wear-resistant, impact-resistant steel with surface hardening to ensure stable long-term operation under high-load production.
Machining Highlights for Plastic Garbage Bin Moulds
Garbage bin moulds are large-size, deep-cavity, heavy-duty structural moulds requiring high strength, rigidity and smooth demoulding. Machining accuracy directly affects product strength, appearance and service life. SINO MOULD focuses on these key aspects:
- Ensure verticality, flatness and concentricity to avoid deformation, tilting or poor lid fitting.Reinforcing Rib & Deep-Cavity Structure Precision
- Accurate machining of ribs, buckles, wheel holes and pedal mechanisms for reliable strength and smooth function.Uniform Surface Treatment
- Consistent polishing or texturing avoids uneven roughness and improves appearance and durability.High-Precision Assembly & Rigidity
Tight parting surfaces, smooth sliders and reliable clamping reduce flash, leakage and downtime.
Mould Flow Analysis for Plastic Garbage Bin Moulds
Using Mouldflow analysis, we simulate the filling, holding, cooling and shrinkage processes of garbage bin moulds. Gate position, runner layout and cooling circuits are optimized to ensure uniform filling, reduce sink marks, warpage and bubbles, and improve product strength and appearance consistency.
