Introduction to Metal Injection Molding (MIM)
Metal Injection Molding (MIM) is a variation on traditional plastic injection molding that enables the fabrication of solid metal parts utilizing injection molding technology. […]
more details in reducing energy and material consumption
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? [...]
The reasons why replacing Metal with Plastics–2
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 [...]
The reasons why replacing Metal with Plastics–1
There are numerous reasons why replacing metal parts with plastic makes sense. Here’s why plastic may be the best option for your parts. […]
Define surface roughness
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 [...]
What is Clamping unit?
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. […]
What is Injection unit?
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. […]
More details about mold design
In addition to runners and gates, there are many other design issues that must be considered in the design of the molds. Firstly, the mold must allow the molten plastic to flow easily into all of the cavities. […]
Introduction to mold channels
In order for the molten plastic to flow into the mold cavities, several channels are integrated into the mold design. First, the molten plastic enters the mold through the sprue. […]
Introduction to Mold base
The mold core and mold cavity are each mounted to the mold base, which is then fixed to the platens inside the injection molding machine. […]
