Plastic broom head injection molding machine is a kind of equipment specially used for producing plastic broom heads.
Plastic broom heads are a common janitorial tool that is usually used for indoor cleaning tasks. Most broom heads are replaced from the handles, making them convenient and cost-effective to maintain.
The plastic broom head is mainly composed of a plastic main frame and a bristle part. The main frame is mainly plastic, which is produced by an injection molding machine to attach the broom handle and fix the bristles. And the frame is usually flat or curved for better contact with the ground. This is followed by the broom head with multiple small holes or clip slots for fixing the bristles (plastic or nylon), which are inserted and fixed by mechanical or hand.
The production of plastic broom heads usually involves injection molding using an injection molding machine. Followed by the flocking process through the flocking machine, and finally assembled into a complete broom on the assembly line.
The working principle of the broom head injection molding machine is similar to the syringe used for injection, it is with the help of the screw of the thrust, the plastic has been plasticized into the molten state of the plastic injection into the closed good broom head mold cavity, after curing and shaping of the products obtained after the process.
Plastic Raw materials for plastic broom heads
PP
Polypropylene is the most commonly used material with good durability, chemical and impact resistance, relatively low cost and suitable for mass production
PE
In particular, high-density polyethylene (HDPE), which is used in the manufacture of plastic mop heads, has good abrasion resistance, flexibility, and chemical resistance.
PVC
PVC has good chemical resistance and is inexpensive for use in low-end products.
ABS
ABS plastic is tough, impact-resistant, and abrasion-resistant, and is mainly for the structural part of the mop head, which requires higher quality.
Depending on the usage scenario and requirements, manufacturers may choose different combinations of plastic materials to achieve the best balance of performance and cost.
The production process of plastic broom head machine
- Mold Design and Fabrication
- Raw material preparation
- Injection Molding Process
- Mold Release and Product Handling
- Assembled bristles
Mold Design and Fabrication
- Mold design: According to the specific shape, size, and function of the broom head, design a suitable mold. The mold has two parts, top and bottom, to form the shape of the broom head.
- Mold Manufacturing: Usually use steel or aluminum to manufacture the mold. The accuracy of the mold determines the quality of the broom head.
Raw material preparation
- Selection of appropriate plastic materials (e.g. polypropylene PP, polyethylene PE, etc.), which are usually in granular form.
- During the manufacturing process, the raw materials may incorporate certain additives, such as colorants or reinforcing materials, to enhance the performance and appearance of the product.
Injection Molding Process
- Heating: The plastic granules are fed into the charging cylinder of the injection molding machine through the charging hopper.
- Heating and Plasticizing: The heater inside the injection molding machine heats the plastic granules to a molten state and mixes them evenly through the rotation of the screw.
- Injection: The screw moves forward and injects the molten plastic into the cavity of the mold through high pressure.
- Filling and cooling: The plastic flows into the mold and fills all the cavities. Inside the mold, the plastic begins to cool and solidify, forming the shape of a broom head.
- Holding and Cooling: After the injection is complete, the plastic inside the mold continues to hold pressure to prevent the plastic from shrinking and causing defects, while cooling continues to allow the plastic to fully cure.
Mold Release and Product Handling
- De-molding: After the mold cools down, the mold opens and the molded broom head is removed from the mold either mechanically or manually.
- Deburring: The product may have a small amount of burrs or workers need to trim excess plastic.
Assembled bristles
At last, plastic bristles can be inserted into the broom head by automatic or manual methods.
Main equipment:
- Injection molding machine: used to heat, plasticize and inject the plastic raw material into the mold to complete the main molding work of the broom head.
- Mold: The mold is a very critical part of the production process, determining the shape and structure of the broom head.
- Auxiliary equipment: Manipulator: for automatic removal of finished products. Cutting machine: for removing burrs and trimming. Brush hair installation machine: for automatic assembly of broom bristles.
Modern broom head production processes are usually equipping with automation equipment. Such as robots and automatic assembly equipment, which can greatly improve production efficiency and precision, reduce manual operations and ensure the stability of mass production.
