The plastic for injection molding chairs is generally PP, and sometimes calcium carbonate (not more than 20%) is added in order to make the product look full, without miniature. PC (fully transparent) plastic is also useful, but there may be many bubbles due to poor exhaust and other reasons, but the cost is higher, and the surface treatment of the steel is also different.

Chair mould has several special requirements:

1, parting line is better, do not grind;

2, the exhaust effect is better, otherwise the plastic products will have black spots, etc., and serious ones will burn;

3, the superposition effect is better, the stack of 10 chairs is vertical and not inclined, the distance between the feet of the two chairs should not exceed 60mm when superimposed, and it should be easy to separate after superposition;

4, the mould should be highly polished, because the chair is a daily necessities, so there can be no flash, burr, etc., to avoid scratching the skin.

Plastic chair mould is generally a cold runner large gate, with a thimble ejection, if it is taken out with a manipulator, the ejection is the top, if it is automatically removed, it is flipped down the top.

 

When it comes to producing chairs, plastic is a popular material choice due to its lightweight and durable nature. There are several types of plastic materials that can be used, each with their own unique properties and benefits.

One common plastic material for chairs is polypropylene. This is a thermoplastic polymer that is known for its strength and resistance to chemicals and heat. Polypropylene chairs are lightweight and easy to clean, making them ideal for outdoor and indoor settings.

Another popular plastic material for chairs is polycarbonate. This material is highly impact-resistant and transparent, making it a great choice for chairs that need to withstand heavy usage. Polycarbonate chairs are also UV-resistant, making them ideal for outdoor use.

Acrylic is another option for producing chairs. This material is similar to polycarbonate in terms of its transparency and impact resistance. However, acrylic chairs tend to be less durable than polycarbonate chairs and are better suited for indoor use.

No matter which plastic material is chosen for producing chairs, it is important to ensure that it is high-quality and meets all safety standards. With the right material and design, plastic chairs can be a versatile and durable seating option for a variety of settings.

 

 

Want to do a chair mould, first of all, you must first choose a good mould company, many companies can do chair mould. However, to make a chair mold, there are still some selection conditions. The scale and equipment of the mould company, the experience of technical personnel, and the ability to respond to emergencies are the embodiment of the strength of the mould company.

The second is the quality requirements, that is, the life of the mould. A good mold can produce millions of sets of moulds, and some play dozens of sets of product moulds to repair. For the mold life should be combined with their own capacity to determine. The mold life is closely related to the hardness of the steel, and the hardness of the chair mould should at least reach HRC33 or more, in order to control the cost, the P20 material is generally used for about 500,000 molds, and the cost of better steel materials should be increased a lot.

There is also the question of the style of the chair. Some customers need to make many kinds of chair moulds, among which, the same style of different flower boards do not need to open a lot of moulds, in this case, only need to open a mould on it, flower boards can be made of multiple inserts, and the inserts can be used to interchange.

 

1.P20 steel

P20 steel is a common mould steel, often used in the manufacture of plastic moulds. Its main features include:

Hardness: The hardness of P20 steel is usually between 28 and 30HRC.

Wear resistance: has good wear resistance, suitable for injection mould.

Processing performance: easy to process, suitable for a variety of processing processes, such as forging, CNC milling rough processing, tempering and so on.

‌Application scenario: often used in the manufacture of plastic chair mould, especially in the injection molding machine mould ‌12.

2.718 steel

718 steel is also a commonly used mould steel, especially suitable for the manufacture of large plastic moulds and hot pressing molds. Its main features include:

Hardness: The hardness of 718 steel is high, can maintain stable performance in high temperature and high pressure environment.

Wear resistance: has good heat resistance and wear resistance, suitable for high temperature and high pressure environment.

‌Application scenario: often used in the manufacture of large plastic moulds, such as chair mould.

When choosing steel, the following factors need to be considered:

Hardness: according to the use of the mould environment and requirements to choose the appropriate hardness.

B.Wear resistance: Ensure that the steel can maintain good wear resistance under high temperature and pressure environment.

C.‌ Processability: Choose the steel that is easy to process to reduce the difficulty and cost of processing.

‌ economy ‌ : Select cost-effective steel according to the budget.

 

 

How big an injection molding machine is needed for a large chair mould? For manufacturers, determining the right injection molding machine size can ensure the production of high-quality products and improve manufacturing efficiency. If the injection molding machine is too small, it may not be able to accommodate the mold and meet the required injection pressure and flow rate. If the injection molding machine is too large, the cost is too high, and it may waste materials and energy.

So, how to determine the size of the injection molding machine required? Here are some factors to consider:

The first is the mould size. The mould size has a great influence on the size of the injection molding machine. Ideally, the injection molding machine should be able to accommodate the size of the mould, and there should be enough space when the mould is loaded.

The second is injection pressure and flow rate. Each injection molding should be based on the production of the product to set the appropriate injection pressure and flow. If the injection pressure and flow rate exceed the capacity of the injection molding machine, the product produced may be defective or fail completely. Therefore, the manufacturer must carefully consider the required injection pressure and flow rate to determine the required injection molding machine size.

Finally, manufacturers should think about future needs, not just current ones. They may need to expand the production scale or increase the product line, which requires the corresponding injection molding machine.

When choosing an injection molding machine, manufacturers should also evaluate other factors such as production costs, energy efficiency, and maintenance costs.

In short, choosing the right injection molding machine size is an important factor in ensuring the production of high-quality products and improving manufacturing efficiency. When choosing the injection molding machine size, it is crucial to consider the mould size, injection pressure and flow rate, and future needs. Manufacturers should also evaluate other factors to ensure that the choices they make are feasible in the long-term plan and are cost-effective.
