Selecting the right plastic increasing molding machine is one of the most important criteria to guide machine parts to be manufactured continuously and technically. Appropriately priced machines will help less and make you stronger. This will give you more parts to supply, make more money and at the same time establish a status as a codable company.

Better yet, you’ll secure long-term customers. Another important criterion for producing efficient and quality parts is choosing a quality mold design.

How can you keep your costs down?

  • Reduce rejection rates (set a goal of <1%)
  • Reduce the energy consumption of all injection molding machines
  • Get ​​rid of spontaneous injection machine downtime (without any breakdowns)
  • Get ​​faster production cycle times

A properly selected plastic injection molding machine will provide you with the points mentioned above.

Here are some of the most common machine choice mistakes and their implications

The most effective way to assess the significance of proper machine selection is to list the most common errors and part productivity and condition consequences during machine selection.

Mistake 1: Buying a used injection machine that is working poorly

The key to buying a reliable used machine is to find one that has been fully inspected and tested before delivery so you don’t suffer production losses due to multiple breakdowns.

Mistake 2: Choosing a large screw diameter

Sometimes large screw diameters can cause poor quality problems due to material deprivation. When small shot sizes and large screw thicknesses are used, the plastic material takes more time to be warmed by the barrel heater than for large shot sizes. Material rejection is more likely if the shot size is small compared to the maximum shot capacity of the injection unit, especially for heat-sensitive materials.

Another disadvantage with large screw thicknesses is the large clipping forces produced during screw revolutions, which can also break the material and cause parts to be rejected.

The molding technique should not be limited by the injection pressure to produce consistently efficient parts. It is recommended to set aside at least 10 percent injection pressure so that the injection casting machine can automatically change to a normal change in thickness of the plastic material. Low injection pressure will produce smaller molds.

Frequently Asked Questions

Daoben has the SOP (Standard Operation Procedure) and all the production steps must follow up this SOP. Every machine needs at least automatic running over 72 hours and must be inspected carefully before shipment.

Actually, the delivery time of the machines is depended on the machine options. Normally, the delivery time of a standard machine could be within 1-2 months.

12 months warranty after shipment for mechanical parts, hydraulic parts, and electric components excluding the screw and barrel 6 months (not including use for recycled material or reclaimed material).

Yes, Daoben will provide one set of standard spare parts to the customer including a heater, filter, screw head, screw washer, checking ring, sealings, etc.
