PTJMould is a professional china plastic injection molding company,we are mainly offer custom plastic injection molding,plastic injection mould design and plastic injection molding manufacturer.

As PTJmould have purchase many plastic injection molding machine already,so we have some 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.

Mistake 3: All-purpose Screws

The main benefit of an all-purpose screw is that they can be utilized with most plastic materials like PE, PP, PET, Nylon, and PC so they’re very adaptable and good for molding companies that mold a range of various materials.

The drawback is that, for a few materials, component types and efficiency rates will be lesser compared to more superior injection casting screw designs like the barrier screw.

Mistake 4: Injection Pressure Controlled

For constantly making the efficient parts the molding technique should not be restricted by the pressure of injection. It is recommended to have at least 10 percent injection pressure aside so that the injection casting machine can automatically tweak to a normal variation in the plastic material thickness. Less injection pressure will create short moldings.

Usually the injection units screw thickness controls the obtainable utmost injection pressure so it is important to select the right diameter when purchasing a plastic injection casting machine.
