Over-mold injection molding and two-shot injection molding are two distinctly different molding methods even though both are used to combine multiple polymers into a single part. Because of this similarity, […]
Choosing plastic mold steel is a very important process in mold manufacturing, because the classification of plastic mold are generally on the length of plastic mold by 5 grades, grade1 is over a million times; grade 2 is 500,000-100 million; grade3 is from 300,000 to 500,000; grade4 is from 100,000 to 300,000, grade 5 is [...]
Candle making is probably one of the earliest dip molding/coating processes used in the industry. It is still in use today. Dip coating has also been an important branch of food processing. For example, chocolate and/or caramel are often coated on many nuts, cookies, and dry or fresh fruits. Dip molding and coating were widely [...]
Metal Injection Molding (MIM) is a variation on traditional plastic injection molding that enables the fabrication of solid metal parts utilizing injection molding technology. […]
Some designers would like to think that making things from recycled materials or designing them for marginally longer life will save the world, but in truth much of it will end up in landfill regardless. Take a drinks bottle – Do you buy a bottle made with recycled content, or use a refillable bottle? [...]
1) gain greater product structural strength That third little pig really knew how to choose the right materials to build a strong house. Choosing plastic over metal gives you products which are light-weight, easier to use and yet possess increased structural strength. Plastic parts can be stronger than metal parts through the use of engineering [...]
There are numerous reasons why replacing metal parts with plastic makes sense. Here’s why plastic may be the best option for your parts. […]
Surface roughness is the measure if the finer surface irregularities in the surface texture. These are the result of the manufacturing process employed to create the surface. Surface roughness Ra is rated as the arithmetic average deviation of the surface valleys and peaks expressed in microinches or micrometers. ISO standards use the term CLA (Center [...]
Prior to the injection of the molten plastic into the mold, the two halves of the mold must first be securely closed by the clamping unit. When the mold is attached to the injection molding machine, each half is fixed to a large plate, called a platen. […]
The injection unit is responsible for both heating and injecting the material into the mold. The first part of this unit is the hopper, a large container into which the raw plastic is poured. The hopper has an open bottom, which allows the material to feed into the barrel. […]
