The Three Step Process of the Plastic Injection Molding Machine

The plastic injection molding machine has changed the fabrication process of plastic products in many different types of industries. Many people do not realize how many different items that they use on a daily basis that are created by these simple machines. Anything that is made of plastic materials is fabricated through the use of one of these devices.

  1. Look around your home, and try to pinpoint some of the items that you presently own that are made from this durable material. Your favorite comb, silverware, the dashboard in your vehicle, your calculator and other items feature this material on them.
  2. The good thing is these machines have made it extremely easy for companies to create products for the general public in a shorter time span. The equipment goes through three different processes, before it delivers the final item that it is purposely trying to make. Obviously, the device is run through a series of computers, which helps speed up the production process.
  3. The third thing that an individual who wishes to utilize one of these devices has to do is create a mold of an item that they are opting to create. The mold will then need to be carefully placed inside of the device. After the mold has been put in place, an individual will then need to feed the necessary materials into the device, where the materials will then be heated to a liquid form.

Tips to Select a Plastic Injection Molding Machine

Choosing the correct plastic injection casting machine is one of the most crucial criteria for creating efficient machining parts constantly and beneficially. The appropriate machine will assist in keeping prices low and turn you more productive. This will let you sell more parts, make more money and simultaneously establish a status as a reliable company.

Even better, you’ll have the safety of long-term customers. The other vital criterion in manufacturing the efficient and quality parts is choosing the quality mold design.

How Can You Keep Your Costs Low?

Reduce rejects rate (set a target <1%)

Cut down the energy use of all injection casting machines

Get rid of spontaneous machine downtime -(without any breakdowns)

Get quicker cycle times

An accurately picked the casting machine will provide you the above mentioned points.

Here are some of the Most Common Machine Choice Mistakes and Their Effects

The most effective way to value the significance of correct machine selection is to list down the most common faults made when choosing machines and the consequences on part productivity and condition.

Mistake 1: Purchasing Used Injection Machines Working Poorly

The key to purchasing a dependable used machine is to look for the one that has been completely examined and checked before delivering it so that you don’t undergo the production loss because of multiple breakdowns.

Mistake 2: Choosing Large Screw Diameters.

Sometimes the big screw diameters can lead to poor quality problems because of the material deprivation. When small shot sizes are utilized with big screw thickness, the plastic material takes more time to get warmed by the barrel heaters as a comparison to the big shot sizes. Material deprivation is more probable to happen if the shot size is undersized as a comparison to the injection unit’s utmost shot capacity, particularly for heat sensitive materials.

The other difficulty with large screw thickness are the big clipping forces produced during screw revolution, this can also break down the material and is probable to cause reject parts.
