Different types of plastic chairs injection molding machines to cope with the production of all kinds of different plastic chairs.
Plastic chair is the dominant seating in modern society, Shapes, colors, and even materials are determined by the fact that they are produced on different plastic chairs injection molding machines.
There are some principles for different types of plastic chairs injection molding machines：
- PP chairs use 700 ton injection molding machine;
- PC chairs use 1200 ton injection molding machine.
Different Styles of plastic chairs
Special design of plastic chair mould
Use different plastic materials with different machine.
Different Styles of Plastic Chairs
Different shapes will make the chair moulds show different variations in three-dimensional dimensions. Therefore different plastic chair injection molding machines have to be adapted to their production.
According to different place, the type of plastic chairs is differnt:
- Outdoor chair;
- PC chair;
- Chiavari chair;
- Acrylic chair;
- Napoleon chair…
We routinely use a variety of plastic chairs injection molding machines ranging from 360-1000t to produce a wide range of chairs, stools and benches.
Special design of plastic chair mould
Special mould design: When the customer’s seat only has a back pattern, we can customize the back inlays in the plastic chair mould to produce different seats.
We can individually customize the inlaid blocks in the mould to produce different seats, which greatly reduces the cost of the mould.
We can also add gas assisted design in the plastic chair mould. The function of gas assisted machine is to add a section of air in the process of injection moulding of cylindrical chair legs and seat back columns, so as to save the raw material to the maximum extent without affecting the structural strength and longitudinal support force of each cylinder at the same time.
Different plastic materials for Different machine
The fluidity of the raw material is the key to the selection of the different materials used for seating in the adapted models.
PP is the most conventional material, while PC has a faster fluidity but is easier to solidify, so it requires a higher injection rate and pressure to inject, and therefore a higher clamping force to ensure that the product does not produce flying edges.
Therefore, in the general production of 556x543x800mm seats, we choose HCK700.
As PC has high transparency and hardness, we need HCK1000 to produce PC seats in the same size.
Chair injection molding production steps:
Chair injection molding involves multiple stages, including mold design, mold manufacturing, injection molding, and subsequent assembly and testing.
The following are detailed steps and related information:
1. Chair mold design and manufacturing:
Chair mold is the core tool for chair injection molding production. Professional mold manufacturing, including ordinary PP chair molds, PC chair molds, etc., and can control gas assisted technology to solve chair weight problems.
The design and production of injection chair molds need to consider factors such as product strength, weight, and molding cycle. For example, gas assisted molds can increase product strength, reduce product weight, and improve molding efficiency.
2. Chair injection molding:
Injection molding is the process of heating plastic raw materials to a molten state and injecting them into a mold, cooling and solidifying them to form chair components.
The Haichen fully automatic injection molding production line can achieve rapid production of small chairs.
In addition, the Haichen 1200 large servo driven injection molding machine is also used for integrated injection molding of Nordic style tables and chairs. Like the Chiavari chair by PC material.
3.Quality control and testing:
The quality control of injection molded chairs is very important. Haichen injection molding machine uses ABS engineering plastic for one-time injection molding of the backrest and seat shell of auditorium seats, which has the characteristics of no deformation, high precision, and corrosion resistance.
Market prospects and development of plastic chair injection molding:
The development trend of the injection molding chair industry shows that the market demand is constantly growing, especially in the field of anti-static disposable injection molding work chairs. In addition, with the increasing awareness of environmental protection, compostable chairs made of bioplastic composite materials are gradually receiving attention.
Chair injection molding production is a complex and intricate process that involves multiple aspects such as mold design and manufacturing, injection molding, automated production, quality control, and market prospects. The specialized division of labor and technological progress in each link have jointly promoted the efficient and high-quality development of chair injection molding production.
Plastic chairs are relatively large plastic products, and will use large and medium-sized machinery of more than 530 to 1,000t. For different plastic chairs solutions, the product material, exterior design and internal structural design should be carefully confirmed, and the choice of different types of plastic chairs injection molding machines.
