1-We need to clean out surface of the mould to make sure the assembly plate is flat. In this can avoid the machine plate not hurt and
Pressured. And also we need to check the parallelism of the cavity and core .
2-We need to clean the surface of the mould surface after finished assembly the moulds on machine. especially the guide the guide structure parts. For example: guidepin, guide bush
3-Make the lubrication oil to the sliding part of the mould
4-make examination of the safety parts on mould

There are so many kinds of plastic chair mould, we have make household chair mould, office chair mould, stadium chair mould, high-end art chair moulds, and some of them are gas-assisted chair mold, we make both cold runner and hot runner chair mould.

Plastic chair mold is usually large, so we usually use P20 for chair mold, some customers have higher requirements, we will use 718H steel. Generally, chair is demoulded from mould by ejection pin or ejection block, many customers will remove the chair by industrial robot, which stacked the chair well. Lots of chair mould can achieve back and seat interchangeable. So customers can use one mold to make 2 or 3 different chairs.

Most chairs are made by PP material, of course, some customers will join fiberglass or calcium carbonate in PP, 10% to 30% can be, according to the customer's requirements. Chairs which use additives will not have as shining surface as pure PP material, but definitely stronger than pure PP chair; because fiberglass or calcium carbonate is cheaper than PP, so the production cost is cheaper than pure PP chair.

If you want to develop plastic chair mould, please contact us, we are chair mould maker; we can give you all kinds of suggestions to help you make chair production easier.

Nearly all plastic molds are custom-made, mould suppliers never make mould ready for sale, unless it is used mold, so the mold delivery time is usually long. Generally, custom plastic mould processing is like this:

-- Customer provides product samples or product design, mould maker make quotes.
-- Customer bargain or confirm the price, then pay, the procedures is the same as general trade.
-- Then mold maker began to design the product or make product design inspection.
-- After customers confirm product design, mold maker will begin mold design, of course, they will ask for some information from customers. For example, matching or assembly requirements, machine parameters, plastics parameters, voltage, etc.
-- if the buy have ability to check the mould design, after design complete, mold maker will send design to customer (here may have design modification or improvement ).
-- After customer confirms mold design, mould processing begins. Generally mould maker will send customer some report or picture to show the mould process conditions.
-- After the first tryout, mould supplier will send customer sample by courier, allowing customers to check whether the sample qualified, and tryout video will also be send; Mold company will improve mould during that time. if the customer confirm the sample, then customer can arrange payment and shipment, if customers are not satisfied with the sample, then continue to negotiate improve mould.

Custom plastic mould is different from buy the product; there is much negotiation and communication between the buyer and seller, buyers have to provide as much information to facilitate the mold company to finish a good mould. If you want to order plastic mold, please contact us. We can offer you a good plastic molding solution.

 Collapsible plastic crate is developed from ordinary plastic crate, and now it is slowly replacing the ordinary crate, because plastic Collapsible crate has a very distinct advantage.

Collapsible crate is strong as ordinary plastic crate, regardless of the load or the strength. Some collapsible crates use even better material than ordinary crate. Collapsible crate biggest advantage is that it can be folded when not loaded, and the folding volume is only 1/4 comparing with its opened, it can greatly reduce transportation costs and storage space; and now the collapsible crate is very convenient to use, easy folding and easy assembly; it has been widely used in various industry, such as manufacturing, agriculture, fisheries, animal husbandry and aquaculture.

Injection molding is not only for plastic molding, there is also having metal alloys injection molding; we call that die casting mould.

Die casting is a method to casting liquid forging; this process can be achieved only on a dedicated die forging machines. Die-cast materials, die-casting machine, die-casting mould are the three elements of production, casting is to organically integrated use these three elements so that they can be stably and efficiently produce the qualified castings.

Die casting mould surface temperature control is very important in the production of high-quality casting. Uneven or improper mold temperature will lead to dimensional instability; it may bring ejection deformation, produce thermal stress, sticking cavity, surface uneven, thermal shrinkage, internal bubbles and other defects. The larger temperature difference will affect some variable factors, such as fill time, cooling time and spraying time etc. Others defects like cold lines, cracks, peeling, ripples, surface holes etc will occur in die casting mold.

Basically all castings need surface treatment or post processing. In recent years, a variety of new die-casting mold surface treatment technologies are emerging, in general can be divided into three types: (1) traditional heat treatment process improvement techniques; (2) surface modification techniques, including surface thermal diffusion treatment, surface strengthening, strengthening EDM technology and so on; (3) coating technologies, including chemical plating and so on.

If you have any demand for die casting moulds, please contact us.

Continue to previous office using PC chair mould design topic,I would like to say something about PC chair mould making and testing.Thanks.

Third, during office using PC chair mould making, we have to make the mould completely according to the mould drawing, it is better not use tool by hand, but use precision tooling machine for all the surface of PC chair mould. If the PC part thickness is not even, the reflect way for light is changed, so we could see clearly about the PC part problem. Sino Mould use high speed milling machine for tooling, that’s why the parting line of the PC chair is very comfortable. Once there has a little tooling mistake, it is better to re-tooling for the whole surface of the chair mould, if you want to use common welding to modify the tooling mistake, you will make the other serious mistake, the PC chair could show clearly where you have made welding on the PC chair mould.

PC chair mould China

Fourth, when the PC chair made ready, we have to do mould testing. During testing, we have to connect the mould temperature controller in order to control mould temperature. We have to design two lines for cooling, one for water cooling, the other line is for oil flow. We need to do PC raw material drying before production, and the PC chair mould temperature is required higher than common material mould.

Sino Mould have strong ability to complete the new office using PC chair mould according to your requirement. Please feel free to contact us if need any more information. Thanks.

Sino supply high quality injection moulds for the customers all over the world. We have rich experience in making different types injection moulds and have strong design ability for novel parts developing, such as office using PC chair moulds, gas-assisted arm chair moulds, foldable crate moulds and so on. Sino Mould could offer you turnkey solution for the injection molding line and mass production plastic products.

Office using PC chair is very popular nowadays as it is transparent and could have different colors. People could get good feeling when working. Sino Mould offer you a fine solution to make qualified office using PC chair moulds.

PC arm chair mould China

Consider PC raw material is transparent, we have to check many things during PC chair mould manufacturing in order to get nice looking PC chair.

First, the steel material for transparent PC mould is required good polishing in order to get shinning surface; PC raw material is quite hard among different plastic raw material, so the hardness grade for steel material is the more the better. The suggest steel material is 718H, DIN1.2738, DIN1,2344 and so on. With good steel material, we could get good appearance office using PC chair sample with long running mould life.

Second, during the mould design, there are some points we have to pay attention on, one is for the injection gate location choosing and injection gate size, it is very important for PC parts molding, it will affect much of product surface, a suitable injection gate location could avoid the flow line and make easy setting during mould running. A suitable injection gate size is for getting qualified product and short time cooling. One is for mold flow before mould design, we could know if the injection is balance and if it is easy for injection or not. The other is with hot runner system, PC mould could not use cold runner system, if use cold runner system, the area near injection gate do not look nice.

I will continue to talk about some notice in my next artical about the office using PC chair moulds,if you have any question,please do not hesitate to contact me.Thanks.
