Sanitation Plastic Trash Can Mold

The sanitary plastic trash can mold is the core equipment for achieving standardized and large-scale production of sanitary plastic trash cans. Its quality directly determines the structural stability, usage performance and production efficiency of the trash cans.

 

1. Mold Materials: Precisely match production requirements to ensure mold durability

 

The material selection for the sanitary plastic trash can mold needs to take into account mold lifespan, molding accuracy and production cost. The core materials are divided into core and cavity materials, mold frame materials and standard accessory materials. Specific selection can be customized according to the customer's production volume requirements and product precision requirements:

 

Core and cavity material: As the core forming components of the mold, the mainstream materials selected are pre-hardened steel (such as P20, 1.2311, P20 + Ni), hard steel (such as H13, 1.2344, NAK80), and stainless steel (such as ASSAB Stavax). Among them, pre-hardened steel is suitable for regular production requirements, with a hardness of up to HRC 30-32, and the mold life is not less than 20-300,000 mold cycles; hard steel, after heat treatment, has a hardness of up to HRC 50-52, and the life can reach 60-800,000 mold cycles; stainless steel has excellent corrosion resistance and the life can exceed 100,000 mold cycles, suitable for producing trash can molds for special environments.

 

Frame material: It is recommended to use Longji standard frames. The mainstream materials are S50C or P20. The pre-hardening hardness should be greater than 30HRC, which can effectively ensure the overall structural strength and assembly accuracy of the molds.

 

Standard accessories: We uniformly select international standard components such as DME and HASCO for all parts, including guide columns, guide sleeves, and push pins, which can enhance the stability of the mold operation and facilitate subsequent maintenance and component replacement.

In addition, the surface of the mold can be treated with texture or polished with a high gloss according to product requirements; the ejection method of the core can be flexibly adopted through structures such as motors, hydraulic cylinders, ejection templates, and pins; the flow channel system supports cold flow channels, hot flow channels, or a combination of cold and hot flow channels, further optimizing production efficiency and product quality.

Based on the customized production capacity of molds, the sanitation plastic trash bins can cover all specifications and capacities. The mainstream capacity range is from 20L to 660L, which can precisely adapt to the different amounts of garbage generated in different scenarios. The conventional core specifications and key parameters are as follows:

 

1.Small capacity (20L - 50L): Covers specifications such as 20L, 30L, 40L, and 50L. Suitable for small public places or enclosed spaces. For instance, the 40L dual-bucket classified trash cans are commonly used in office buildings and small supermarkets; the 50L trash cans are suitable for community unit buildings, small canteens, etc. Their barrel wall thickness is ≥ 3mm and the barrel bottom thickness is ≥ 4mm, ensuring both portability and durability.

 

2. Medium capacity (100L - 120L): 100L and 120L are the most commonly used outdoor specifications in daily life, widely applied in residential areas, schools, parks, urban streets and other scenarios. Taking the 120L trash can as an example, its wall thickness is ≥ 4mm, the bottom thickness is ≥ 5mm, and it is equipped with rollers with a diameter of ≥ 185mm, which makes it convenient to move and can meet the needs of centralized collection of medium-sized garbage.

 

3. Large capacity (240L - 660L): 240L and 660L are the core specifications for municipal sanitation. They are suitable for scenarios with high garbage production such as streets, large communities, industrial parks, and transportation hubs. Among them, the 240L trash can can be adapted to various operation modes of garbage trucks. The dimensions of the long × wide × height are divided into 740 × 585 × 1070mm (side step type) and 710 × 570 × 1070mm (middle step type) according to structural differences; the 660L trash can is specially designed for compressive garbage trucks and has an automatic dumping function. The wall thickness is ≥ 5mm and the roller diameter is ≥ 200mm, which can easily meet the requirements of high-intensity handling and garbage carrying.
