The minimum machine to produce plastic chairs is a 800-1000t Plastic Chair making Machine. It is a special injection moulding machine specialising in the production of plastic chairs.
Plastic chair injection molding machines are used to produce plastic chairs by heating and melting the plastic raw material and then injecting it under high pressure into the plastic chair mould.
The model of plastic chair injection molding machine is selected based on the size, weight and type of raw material of the plastic chair and other production requirements.
How to choose an injection molding machine according to the size of the plastic chair
The size of the plastic chair is the most basic consideration for the entire injection molding production project.
It has a crucial impact on the selection of injection molding machines, and the following are six key factors:
- Plastic chair mould size and weight
- Plastic type and quantity
- Finished product size and appearance requirements
- Production speed and efficiency
- Mould design and process optimisation
- Equipment performance and maintenance
Plastic chair mould size and weight:
When choosing an injection molding machine, first of all, make sure that its clamping force can meet the clamping requirements of the mould.
Meanwhile the injection volume of the injection molding machine should match the capacity of the mould.
Plastic type and quantity:
Different plastic chair materials with different fluidity, shrinkage and other characteristics, you need to choose the injection molding machine that can adapt to the characteristics of the plastic used.
Finished product size and appearance requirements:
According to the specific size and appearance requirements of the plastic chair, choose the injection molding machine that can achieve high precision molding.
And through the optimisation of process parameters (such as injection pressure, holding pressure, cooling time, etc.) to improve product quality.
Production speed and efficiency:
Select the suitable injection molding machine model according to the production demand.
Make sure it can meet the requirements of production speed and efficiency.
Mould design and process optimisation:
Use CAE technology and numerical simulation tools (such as Moldflow) to optimize the plastic chair mould structure and injection process.
To reduce warpage deformation and other defects.
Equipment performance and maintenance:
Choose the injection molding machine with stable performance and easy maintenance.
To reduce production costs and extend equipment life.
By comprehensively considering the above factors, the most suitable injection molding machine model for the production of plastic chairs can be selected.
The impact of different plastic chair material types on the choice of injection molding machine
Different plastic chair material types have different chemical properties and differences in physical properties such as liquid flow.
These different characteristics have a great impact on the choice of injection molding machine.
Here are some examples:
- Polypropylene (PP)
- Glass fibre reinforced polypropylene composite (PP+30GF)
- PC
- PA66
- Polyimide (PI)
Polypropylene (PP):
A common material for injection molding of plastic chairs.
It is necessary to choose an injection molding machine that can handle lighter materials and has a high cooling efficiency.
To ensure the quality of molding and production efficiency.
Glass fibre reinforced polypropylene composite (PP+30GF):
This material is used for plastic parking wedge injection molding.
Need to choose the injection molding machine that can withstand higher injection pressure and temperature.
And optimise the mould design to reduce warpage and deformation.
PC
And polycarbonate (PC) has poor fluidity.
Need higher injection pressure and slower injection speed.
And the plasticising system of the injection molding machine needs to provide enough heat to ensure that the material is uniformly plasticised.
PA66:
Used in automotive seat guide bar injection molding.
Need to choose high precision, good exhaust performance of the injection molding machine.
To avoid surface defects such as local bright.
Polyimide (PI) :
Used for automotive thrust pads injection molding.
Need to choose the injection molding machine that can precisely control the temperature and pressure.
To ensure excellent mechanical properties.
The physical and chemical properties of different plastic materials will affect the choice of injection molding machine.
This includes the need for injection pressure, temperature control, and cooling system design.
