How Right Plastic Injection Molding Machine Maximizes Your Manufacturing Process?

‘Bigger the better’ is not always the case when it comes to the identifying the press size. Injection press keeps the mold shut with bigger parts needing more force and tonnage. Your plastic injection molding company will help you to determine which machine is best suitable for your project to minimize the overall cost.

                                    

What is Injection Press?

Plastic injection molding machine is a machine that is used for the production of plastic products via an injection molding process.

How to Calculate Right Press Size for Your Project?

General calculation for determining your press size: Pressure (lb/in2) x Projected Area (in2) = Force (lb.)

a) Estimate Your Press Size

Although the plastic injection molder will help you identify the size of machine required, a skilled engineer or project designer will offer you a good piece of basic information. By knowing what size of machine you will need, you can better cater your demands well.

b) Calculate Total Projected Shot Volume and Shut Off Area

It is essential to calculate shut off area (area consisting of the space which is 90 degrees to the direction of injection molding machine platens) while determining the press size for the plastic parts. A Shot volume will guarantee you that your barrel has sufficient capacity.

                            

c) Know How Much Pressure or Force You Will Need

Pressure plays a vital role in the entire quality of the plastic parts. Too much or too less pressure can cause many problems like viscosity and flashing. Another thing to note is that different plastic compounds react differently under pressure depending on their Melt Flow Index (MFI). It measures the flow of thermoplastic polymer. The higher the MFI, the higher pressure is required to make a successful plastic part.

d) Hire Injection Molding Company

After determining the press size, hunt for the best plastic manufacturing company like Nubs Plastics. The molders are intelligent and knowledgeable. They complete your project in the fastest possible time. Also, if you are working on a complex mold, seek for the agency that can design and create the mold for you. 

They also have a better understanding and know how to maximize your manufacturing process. They will provide you with the needed tools. These mold manufacturers use world-class molding facilities and latest technology that have state-of-the-art manufacturing capabilities. They use energy efficient plastic injection molding machines that deliver better performance.

Just note that big plastic injection molding machines are usually high cost. They take big molds, and these multiple molds help to lower the price per part. Thus, picking the right press will balance the beforehand tool expenses with the long-term manufacturing process.
