Choosing the right plastic injection molding machine is one of the most important criteria for creating efficient and profitable machining spare parts. the right machine will help keep prices low and make you more productive. this will allow you to sell more parts, make more money and at the same time establish your status as a reliable company.

Even better, you'll have long-term customer security. Another important criterion in the efficient and quality manufacture of spare parts is choosing a quality mold design.

How can you keep costs low?

• Reduce rejection rate (set target <1%)
• Reduce energy consumption of all injection molding machines
• Get rid of spontaneous engine downtime - (without any damage)
• Get faster production cycle times

Accurately selected plastic injection molding machine will give you the above-mentioned points.

Engine Selection Errors And Their Effects

Here are some of the most common engine selection errors and their effects.

The most effective way to assess the importance of correct machine selection is to list the most common mistakes made when selecting a machine and their consequences on productivity and component conditions.

Mistake 1: buying a used injection machine that doesn't work well

the key to buying a reliable used machine is to look for one that has been thoroughly inspected and inspected before shipping so you don't suffer a production loss due to multiple breakdowns.

Mistake 2: Choose a large screw diameter.

Sometimes the large diameter of the screw can cause a poor quality problem due to a lack of material. when a small shot size is used with a large screw thickness, the plastic material takes more time to be warmed up by the barrel heater in comparison to large shot size. material shortages are more likely to occur if the shot size is too small compared to the injection unit's maximum shooting capacity, especially for heat-sensitive materials.

Another difficulty with large screw thicknesses is the large clipping force generated during screw revolution, this can also break the material and possibly cause the part to be rejected.

Mistake 3: All-purpose screw

The main benefit of the general purpose screw is that it can be used with most plastic materials such as PE, PP, PET, nylon and PC making it highly adaptable and great for printing companies that make up a wide variety of materials.

The disadvantage is that, for some materials, the type of component and the efficiency level will be lower compared to superior screw design injection molding machines such as barrier screws.

Mistake 4: Injection pressure controlled

In order to make constantly efficient parts, the molding technique should not be limited by injection pressure. it is recommended to have at least 10 per cent injection pressure so that the injection casting machine can automatically change the normal variations in the plastic material thickness. less injection pressure will make the mold short.

Usually, the thickness of the injection unit screw controls the maximum injection pressure that can be obtained so it is important to choose the right diameter when purchasing a plastic injection molding machine.

Hope this article helps you in choosing the right plastic injection molding machine for your contract manufacturing business.
