What Mistakes to Avoid When Buying Plastic Injection Moulding Machine

The best way to improve any process is to identify the flaws and rectify them. And this applies when you are buying a plastic injection moulding machine. Once you know the most common mistakes in purchasing, you can make your buy perfect. This post shares these mistakes to help you buy the best plastic injection press.

Injection moulding machine is for manufacturing plastic products. It uses the injection moulding process to produce high-quality parts. But a wrong machine can produce substandard quality. Avoid the mistakes listed here while you buy.

Tips to Select Right Injection Plastic Machine

Businesses can stay away from these mistakes to select the correct equipment. This is important because the right machine is important for successful business.

#1. Machines with Non-Working Condition

Even when you buy second-hand equipment, you need to be careful about quality. A machine that is not working is not worth buying. The reason is you cannot inspect it and check its performance. Hence, never go for a machine that is already broken or not working.

#2. Selecting Faulty Machines

If the machine is in a working condition, buyers tend to ignore its faults. Consult an expert operator to check the machine. Do not buy the equipment if it shows signs of any serious issue. This might result in degradation of the parts. Getting an inspection is the best way to avoid this mistake.

#3. Machines with Large Screws

Yet another common mistake while buying a plastic injection moulding machine is to choose screws with large diameters. Screws with large diameters will cause quality issues. This will result in poor quality of production. It will deteriorate the material and the parts.

#4. Ignoring Diameter and Pressure

Many buyers do not give proper attention to the diameter of the injection unit. The screw diameter regulates the pressure. The wrong diameter will limit the pressure. Limit on the pressure is likely to damage the moulding process. Select a diameter so that you should have a minimum of 10% injection pressure. This will allow the machine to adjust to the variations of the viscosity of the product.

#5. Ignoring Clamp Tonnage Requirement

This means the clamp force that machine needs during the process. If the material is thicker, greater force is good. Never ignore the amount of clamp tonnage requirement. If the tonnage is low, the quality of the products will be poor. It is better you buy a machine with good clamp tonnage.

If clamp force is lower than adequate, lots of quality issues arise. As a result, the products will have poor finishing, size variation, and inconsistent weight.

If the clamp tonnage is not proper, the machine will attract more wear and tear. The mistakes listed above are the most important ones. Other common mistakes are improper operation and selecting very cheap.

When you are buying a usedmachine, remember that you will get what you pay for. Always avoid making a decision on the basis of only price criteria. Focus on the level of wear and tear of the equipment and not just cheaper price. A right machine will give you smooth and quality production for a long time.
