Plastic Moulding

The demand of plastic based consumer products in increasing day by day. The cost of material as well as the manufacturing synthetic products is relatively low. Therefore the need of such type of products is on the rise today. Plastics are nonmetallic compounds. It can be molded into several forms. Besides it can be hardened for commercial use.

Even the mouse and keyboard we are suing are made through PVC molding.

Basically in plastic moulding molten liquid is inserted into a ready shaped mold. Then it will be allowed to cool. After then the mold will be removed. For example if it is a mold of the bottle then after cooling we get a bottle. Plastic mold for sale in China can also custom mold a variety of products. The products include office trays and boxes, traffic signage and displays for product and marketing promotions, barricades, barriers and cabinets etc.

If you are planning to move in to plastic molding and plastic mold business, first you need to find a Chinese mold partner and you need to know the different processed. Go through the details of every process and collect as much information as you can. And finally choose a process that fits you budget and resources. Let’s get some information about various plastic molding methods.

Blow molding is a process that begins by the melting of the liquid plastic in the chamber of the machine. Then the liquefied plastic is sent to the desired shape. This type of process specializes in creating the hollow products that includes bottles, hoses, motorcycle fuel tanks and other hollow products. In this method the air poured in the mold. Then it will harden and thus it creates the desired shape. Then the mold is pulled out through a mold cavity.

Care and use of your plastic mould

Depending on the material your plastic mold is made out of, you will need some sort of lubricant to make it possible to remove your casting from the mold. Concrete will stick to some types of molds better than others. There are commercially produced mold released if you are inclined to use them. Personally in think there are a waste of money.

I have found that motor oil, Vaseline or petroleum jelly. Cooking spray on lubricants used in the automotive industry work well and are cheap. Surprisingly cooking spray does not working very well and in my opinion should not be on the list. I know why but I have never had a hell of a lot of luck with. Maybe it is because I bought the cheap stuff I do not know. Petroleum jelly is best used if you have wooden mold because it does not soak in like oil does. Be generous with it. Especially on new wood.

I am not going to mention cooking spray, because I never use it. But spray on oils is easy to use and work well on any metal or plastic mold, however I have to say that my favorite is 10 weight engine oil. It is around a dollar a quart, buy the cheapest stuff you can find. It is easy to use. Just pour some on a rag and rub it on your mold. The important thing is to make sure that you got whatever lube you are using into all the corners. And that is not puddle up anywhere.

Depending on the size of the casting, you may decide to put in some wire mesh for reinforcing. I do not usually bother if it is something I will be hanging however if you are casting steppingstones or something like that is a good idea to use some form of reinforcement. A general rule for me is anything over a foot square will have reinforcement. If you are making a hanging, be sure to have the hangar ready to insert. You do not want to be looking for something to make out of in the middle of casting it.

Once you have used your plastic mold and removed your casting another very important thing is to clean you mold, immediately. Before you put it away. I have found the best thing to use is ordinary liquid dish soap. Like you use the sink, not the still from the dish-washing machine. Be sure you do a good job and then hang up you mold out for the sun and it will server you for a long time.
