There are a zillion types of items that we make use of in our day to day activities and perhaps the most used item is the synthetic, non metallic plastic ones. From the computer that you are using right now to buckets and egg crates; whatever you can think of is made up of plastic. There are a number of reasons for its usage. It is a bad conductor of heat and electricity which makes it suitable for numerous usages and simultaneously makes it safe for children. It is also very light weight, hard and is resistant to scratches, which makes it ideal for many types of day to day usable items.

choose the correct steel for mould base and mould main steel. for example, if you need to make a 4 cavities crate mould, then you need to make to use a pre-hardened steel with HRC bigger then 33 for mould base. You have to choose the correct steel or material for the durable mould components. make the correct harden treatment to each steel piece and make the steel hardness controlled, you can not make it too hard. the moving area or guiding system of crate mould must be very precise machining processed. Any hand working on it is not acceptable. 

Large scale manufacturing of everyday items made of primarily plastics, etc. has been the forte of Chinese manufacturers. It is common knowledge that China has always been known for its poor quality of products which it peddled cheap and there was no way one could have business with these guys without being swindled in case of production. Slowly the Chinese manufacturers came to be known the world over for their ineptitude and the absolutely poor variety of their goods which slowly became a reputation for incompetence and swindling. This collective sentiment proved to be quite a back breaking blow for the country as its production sectors suffered and its workers were affected.

Polishing is essentially the removal of metal by the action of free abrasive grains carried to the work piece by a tool.Here is several reasons for plastic mold polishing are liseted below: 1)Plastic mold polishing may achieve special optical properties in a product,will enlight beams pass through the produt wall(compact disc,mirrors,etc),any major unevenness or waviness will distort the light and result in poor performance of the product. 2)Plastic mold polishing may enhance the appearance of the product,This is the most common requirement in plastic mold.It should be noted,however,that th appearance often is required for the visible outside only.Often,no polish is required on the seen inside of the product,and the finish there need not be better than that required for easy ejection of the product from the mold.for clear plastic products where the inside finish as the outside of the product. 3)Plastic mold polishing may faciliate ejection.This applies generally produced by deep recesses in the cavity or where there is little draft angle specified,the cavity must also be free of roughness that may prevent easy ejection. 4)Plastic mold polish may prevent stress risers in a product.Any sharp indent or corner in hardened mold steel,usually created during grinding,will increase the rish of breakage caused by stress concentration.Such corners must be polished to remove the sharp"gouges".

PMMA is a kind of non figuration material, with large moisture absorption. We need to do drying before molding. The drying temperature is between 80-90℃ lasted for 2-4hours and the thickness for the material is about 30-40mm. We could dry the PMMA raw material to 0.03% for the water content, and then the dried material could be used for molding.

During 11 years of SINO team's creating, in the starting of SINO MOULD, we got to know that the workmanship is the most important at that time, and we know the workers who are dealing with air conditioner moulds or other home appliance moulds, we trust that their quality mentality will be better then the people who are dealing with motor cycle moulds...from that time, our HR department choosed the people who came to SINO. Most of our top managers and designers were dealed with air conditioner moulds or other home appliance moulds, untill now we have made many air conditioner moulds, such like air conditioner housing moulds, air conditioner mask moulds, air conditioner fan mould, air conditioner grille moulds...for the grile and mask moulds, we use DIN 1. 2316 tempering steel for cavities long lasting polishing and DIN 1. 2738 for the core side.

Plastic mould is a form of plastic setting material that is industrially used to forge different shapes and sizes. There are umpteen ways of providing shapes to plastic and thus, plastic is available in various sizes. for plastic molding there are two types of molding plastic- thermosetting plastic and thermoplastic. The basic difference between the two is that, thermosets are resistive to higher temperatures where as thermoplastics melt under high temperature. Thermoplastic are ideal for plastic mould as they can be reshaped into another object under the influence of high temperatures. The one dimensional polymers that comprise thermoplastics account for its reshape ability. However, the three dimensional polymers don't allow thermosets to wilt under extreme conditions and it retains its original shape.

Paint bucket mould and plastic moulded paint bucket. The technical point for the paint bucket is the paint bucket wall essesntric and ejection system. for the eccessntric, we have talked on the page: www.cnmould.com/pail-mould.html for how to make the ejection smoothly, automaticly and safely... this is the topic which we should talke, as because paint bucket is different as all the other kinds of bucket, there is one undercut on the edge of the bucket mouth, and this undercut (rib) need to be strippered before it drop down. If there is any other strength ribs on the edge of the bucket, then we need to use angle lifts to make the paint bucket mould ejection. Sino Mould made more then 1000 sets of paint bucket during these 11 years, we have very strong technical knowledge and experience on paint bucket mould design and manfuacturing.

Molding parts: We need molding materials shape, structure, size of the parts, usually by the core (punch), concave cavity model, and thread core, blocks etc. System preference: Injection machine nozzle to close cavity and it will be used for molten plastic, normally by the mainstream way, distributors channel, gate and the cold slug well. Guiding Parts: We guaranteed that the dynamic model and the fixed model can be the accurate alignment for that time when closed and guide arrangement of components are working properly like function orientation, positioning, it is composed to guide pin and guide bush, some of the mould on the ejection plate set up guide parts, reliable that the demoulding mechanism so ensure the smooth movement.
