Plastic bowl injection molding machine is a machine for manufacturing plastic bowls.
Generally speaking, a plastic bowl refers to a non-toxic and harmless bowl made of food-grade PP material.
It can be heated directly in a microwave oven, is easy to clean and has a smooth surface.
This type of bowl is generally produced by injection molding machines.
The plastic bowl injection molding machine is a highly efficient and precise industrial device.
It injects molten plastic into molds and cools them to form the shape.
It is specifically designed for the mass production of various plastic bowls.
Its core advantages lie in the automation control (PLC), high clamping force suitable for large products, and the flexibility of replaceable molds.
When making a purchase, it is necessary to pay close attention to parameters such as injection volume, clamping force, mold compatibility and material adaptability.
What is a Plastic Bowls injection molding machine?
Plastic bowls injection molding machines are the main molding equipment that use plastic molding molds to produce plastic products of various shapes from thermoplastic or thermosetting plastics.
Its working principle is to heat and melt the plastic in the heating cylinder of the injection molding machine.
Then inject it into the preset mold through a plunger or reciprocating screw.
And cool and solidify it in the mold to form the plastic product of the required shape.

The raw materials of plastic bowls
- Polypropylene (PP)
- Polystyrene (PS)
- Polycarbonate (PC)
Polypropylene (PP)
When it comes to PP plastic bowls, PP scientific name polypropylene.
Is a non-polar crystalline polymer with good heat resistance and chemical stability.
Polystyrene (PS)
Manufacturers polymerize styrene to produce PS plastic bowls, which commonly serve as containers in instant noodle boxes and fast food boxes.
But the temperature is too high to release harmful substances.
Polycarbonate (PC)
When it comes to PC plastic bowls, PC is a material with high transparency and good impact resistance, but the cost is higher.
Design the mould for plastic bowls
- Plastic bowl mould
- Mould Cooling System Design
Plastic bowl mould
Plastic bowl molds are an important part of production, directly affecting the forming quality and precision of plastic bowls.
When designing a plastic container injection mould, designers must consider numerous factors to ensure it efficiently and accurately produces high-quality plastic bowls.
First of all, carry out a detailed design based on the shape and size of the plastic bowl.
Secondly, it is necessary to select appropriate materials to ensure the strength and durability of the mold.
And the mold has sufficient strength and rigidity to withstand the pressure during the injection molding process.
It is important to ensure that the molten plastic is uniformly and smoothly injected into the mold when designing the nozzle, gate and runner to avoid bubbles and shrinkage.
Which could lead to defects in the plastic bowl.
Mould Cooling System Design
The cooling system is an important component of the mold.
It is used to control the cooling rate of plastic raw materials in the mold.
This system will directly affect the forming quality and surface finish of the plastic bowl.
It is necessary to design a reasonable cooling circuit according to the type of plastic and molding requirements.
Factors to consider when choosing an plastic bowls injection molding machine
- Product Requirements
- Mold size
- Injection volume
- Clamping force
- Tonnage
Product Requirements
The size, weight and complexity of the plastic bowl determine its optimal machine size.
Generally speaking, the larger the plastic bowl is, the larger the size of the machine will be.
Mold size
The size of the injection mold determines the required machine.
The larger the mold is, the larger the machine will be.
The size of the mold depends on the size of the product, that is, the size of the plastic bowl.
Injection volume
The amount of plastic required for each injection in injection molding determines the size of the machine.
The larger the injection volume is, the larger the machine size will be.
Clamping force
The clamping force required to keep the mold closed during the injection molding process determines its size.
The stronger the clamping unit is, the larger the machine will be.
Tonnage
The required tonnage is calculated by multiplying the projected area of the formed part by the pressure needed to inject the plastic material into the mold.
This calculation determines the force required to keep the mold closed during the injection process.
