How to Make EPS Foam

EPS foam is a highly durable material that is used in a large number of consumer products. EPS stands for Expandable Polystyrene. This expanding foam compound is an excellent insulating material. It is used in refrigerators, coolers, helmets and many other products that are used every day. The large number of uses for EPS foam creates a high demand that makes this a very profitable business to be part of. If you have a manufacturing background, it is entirely possible to make EPS foam products yourself.

Impregnate the polystyrene resin granules with the blowing agent. When making EPS foam, Pentane Gas (C5H12) is normally used as the blowing agent. A small amount of pentane gas is injected into the resin in a process known as Polymerization.

Begin the pre-expansion process. After the resin granules have been impregnated, place them into your steamer and use steam to heat the granules. The heat will cause a reaction with the granules and the blowing agent, and will cause the polystyrene granules to expand to 50 times their original size. At this stage you have a large number of individual foam pellets that are ready to be molded.

Decide on what method of molding your will use on your EPS foam. There are two standard options for molding. The first method is to use a “shape molding” machine. This method will mold your foam to the precise size and shape of the product being developed. The second option is to use a “block molding” machine. Doing block molding creates large blocks or even sheets of EPS foam, which can later be cut to the size and shape that the customer requires. It is important to decide which method applies to the EPS foam you will make, so that you can choose an appropriate molding machine.

Pour the EPS granules into your mold and complete a second heating. The second time the granules are heated with steam, they will swell within the mold and become pressed together into one solid piece of foam. It is this mold heating process that transforms them from individual grains to a sheet of EPS foam.

Remove the EPS foam product from the eps foam mold and allow it to cool. The cooling time will depend on how large your foam item is. Allow the foam to sit and cool until it has reached room temperature. Inspect the mold for any cracks or damage before approving it for use.

EPS foam cutting machine works

The EPS foam cutting machine is light and strong with amazing cutting accuracy and repeatability. The heating wire/fan box is a place for fixing the heating wire. When cutting, the micro-fan is used to cool the heating wire, and a special spring is used to compensate the elongation of the heating wire after being heated. High-performance heating wire, this high-life alloy wire is made of nickel, chrome, cobalt, molybdenum and titanium. It is long in length and can speed up cutting and has a long life. The EPS cutter motion analysis processing software controls the fully automatic turntable so that it can cut rotating bodies such as cylinders and spheres. The side bracket is a fully automated tool controlled by EPS cutter motion analysis software that allows you to cut out all possible rotating bodies such as cylinders, small pillars and more. The material is mounted on a nail located on the nail plate.

High-performance heating wire, this high-life alloy wire is composed of nickel, chrome, cobalt, molybdenum and titanium. It is long-extendable, which can speed up the cutting speed and has a long life. The speed is not very fast, the amount of glue is relatively small, causing the raw material to be plasticized too much, and the particle material slips in the barrel, causing the screw speed to fluctuate, causing the extrusion pressure to fluctuate, resulting in temperature control imbalance. Therefore, before the start-up of the insulation extrusion board manufacturer, all preparations should be made to minimize the waiting time during the startup temperature rise process, and the replacement template should be fast and neat. If the screw of the equipment used is cooled by oil cooling, it is related to the setting of the instrument in the mold thermostat, the smoothness of the pipeline, and the oil quality. If the equipment (screw and barrel) is cooled by circulating water, scale and solenoid valve failure are the main factors.
