Plastic bowl injection molding machine is an industrial equipment specially used for producing plastic bowls. Its core working principle is to heat and melt thermoplastic plastic (such as food-grade polypropylene PP), inject it into the mold cavity under high pressure, and form a bowl-shaped product after cooling and solidification.
The steps of Haichen Machinery injection molding machine: injection, cooling, demoulding and post-processing, and also mentioned the use of servo motors and energy-saving design. Select materials such as food-grade PP, machine model HCK 110 tons is suitable for bowls with a diameter of 15 cm.
When selecting aplastic bowl injection machine, you first need to determine the type and specification of the machine based on the material properties, mould size and moulding requirements of the plastic bowl.
Four key points to select bowl injection plastic machine
When selecting an injection moulding machine, the following points are the main configuration parameters:
- Injection volume and clamping force
- Tie bar spacing mould size
- Plastic properties:
- Injection volume and speed
Injection volume and clamping force:
Calculate the required injection volume based on the volume and weight of the plastic bowl and select the appropriate screw diameter and injection pressure.
To ensure that the mould can withstand the pressure during the moulding process.
Tie bar spacing mould size:
Ensure that the column spacing, minimum mould thickness, maximum opening distance and ejector height of the injection moulding machine can adapt to the designed dimensions of the mould.
Plastic properties:
According to the characteristics of PP material, choose the appropriate screw design and injection pressure.
To ensure good plasticising ability and moulding effect.
Injection volume and speed:
According to the weight of the product per mould and the requirement of moulding speed, choose the suitable injection volume and injection speed
to improve productivity and reduce material waste.
Through these steps, you can ensure that the injection moulding machine you choose can meet the production requirements of plastic bowls and ensure the quality and moulding efficiency of the products.
How to choose the right injection moulding machine according to the plastic bowl size?
Choosing the right type of plastic bowl injection moulding machine requires considering the size of the plastic bowl.
As the most basic identification of size this information is important.
Here are some detailed steps and suggestions:
- Determine the injection volume
- Plastic bowl mould size and weight
- Properties of plastic materials
Determine the injection volume:
First of all, you need to define the production size of the plastic bowl and the injection volume.
Injection volume is the amount of plastic filled into the mould per injection.
The size of the injection volume directly affects the choice of injection moulding machine.
For example, if the shape of the plastic bowl produced is large, the injection volume is larger.
It is necessary to choose an injection moulding machine with larger injection capacity.
Plastic bowl mould size and weight:
The size and weight of the plastic bowl mould is also an important basis for choosing an injection moulding machine.
Larger moulds usually require stronger injection forces and higher clamping forces.
Therefore, when choosing an injection moulding machine, you should ensure that it is able to support the weight of the mould and provide sufficient injection force.
Properties of plastic materials:
Different plastic materials have different physical and chemical properties, which affect the temperature, pressure and cooling time during the injection moulding process.
For example, polypropylene (PP) and ABS plastics have different temperature and pressure requirements during the injection moulding process.
Therefore, the choice of injection moulding machine should be based on the actual material of the plastic bowl to be produced.
Types of plastic bowl injection moulding machines to choose from
There are various types of plastic bowl injection moulding machines and there are many angles to choose from .
Here are some key points:
- Principles of injection moulding machine selection
- Injection moulding machine type
- Intelligence and automation
- Equipment cost and maintenance
Principles of injection moulding machine selection:
The selection of the injection moulding machine should be based on the size and weight of the mould required for the moulding of the parts.
The type and quantity of plastic used, the appearance of the finished product size and moulding requirements.
For products such as plastic bowls, it is usually necessary to choose an injection moulding machine that can adapt to different plastic materials (e.g. ABS and modified PP).
Injection moulding machine type:
Injection moulding machines are mainly classified into all-hydraulic, all-electric and electric/hydraulic composite types.
All-electric injection moulding machines are suitable for small and medium-sized injection moulding machines to produce high-grade precision and small precision parts.
For large or complexly constructed plastic bowls, an all-hydraulic or electric/hydraulic composite injection moulding machine may be required.
These machines are capable of providing higher clamping force and more consistent moulding performance.
Intelligence and automation:
The use of mould flow analysis software, such as Moldflow, can optimise injection process parameters and improve the success rate of one-off mould trials.
High-end injection moulding machines are usually equipped with high-precision and long-life injection moulding systems, enabling high-speed, high-precision and intelligent production.
Equipment cost and maintenance:
All-electric injection moulding machines are more expensive, but with low maintenance costs, they are suitable for long-term use.
Electric-hydraulic hybrid injection moulding machine combines the advantages of electric and hydraulic, with high cost performance.
When choosing a plastic bowl injection moulding machine, the decision should be based on the specific mould design, plastic material, moulding process requirements and production scale.
If the production scale is large and the requirement for product quality is high, you can choose all-electric or electric/hydraulic composite injection moulding machine.
If the budget is limited and the requirement of precision is not high, then you can choose general-purpose injection moulding machine.
