The Hot Wire Foam EPS Cutting Machine

Hot wire foam EPS cutting machine will cut different types of foam, from insulation to fabrication, from logos, surfboards and signs to crown moldings and concrete molds . Foam cutting machines have many applications. They can be used to cut architectural shapes, for packaging, building, construction, hobbies, RC Planes, sculptures, monuments, theme parks, props, aeronautics, aerospace and much more.

What are the main components that a foam EPS cutting machine is made of?The software is divided into two sections design software to design the shapes to be cut, and the cutting software that controls the machine;The hot wire tensioning mechanism;Effective cutting sizes for the horizontal, vertical and the wire length;Number of axis a 4 axis machine will be able to cut tapered shapes (like a cone or a jet wing)

Here are some features to look for in a hot wire foam EPS cutting machine:
For production of crown molding: Multiple wires from 3 to 8 wires will increase the cutting capacity from 2 to 7 times;8 foot effective wire length dont settle for a 4 machine;If primary use of the machine is to cut logos and signs a smaller machine will do the job;Cutting speed mostly material dependent as a rule of thumb: the higher the foam density the slower the cutting speed.

EPS Cutting Machine-- How Is It Manufactured & Molded

EPS cutting machine starts at very small beads - similar to sand in texture called polystyrene - the raw material is called Styrene. Styrene can be found nearly everywhere, in your local food store and the local electronics stores.The plastic utensils are made of - Styrene, CD cases and cloth hangers - all made of Styrene EPS which means Expanded Polystyrene, starts as the small beads.

The next step in the process is to "blow" these small beads into larger beads about 50 times its original size. Depending on the density required, the beads are blown using steam in a machine called "expander" The EPS cutting machine can be a simple machine that a worker places the raw material, and then turns on the steam, or an automatic machine where the material is weighed automatically Steam, then is enables (automatically) and then stopped. Pre- expanders for the so- called "second pass expansion" of already expanded materials are equipped with an especially large feed screw in order to transport the already expanded material to be steamed again. All pre- expanders have in common that the completely expanded beads trickle into a so- called fluid bed dryer where they are dried and stabilized before they are transported into the storage silos.

Continuous pre- expanders are operated without pressure and are equipped with an open- top agitator tank in which raw material is continuously fed from the bottom by an adjustable screw conveyor.. Steam is "also fed continuously into the pre- EPS cutting machine room through openings that are positioned shortly above the tank bottom. An agitator and fixed breaker rods make it more difficult for bead clusters to develop; they keep the beads in motion and make sure that al ready pre-expanded beads of lower density move to the top of the bead bulk and fall into a shaft through a height- adjustable discharge opening.

The two most common blowing agents used are pentane and carbon dioxide - neither contains CFCs. This process - polymerization - fills the polystyrene with millions of air pockets, which helps it to expand and also gives it a low thermal conductivity. During expansion, the product can be molded into a variety of shapes and sizes. The final product is 90% air, but amazingly, EPS can have a compressed strength up to 40 psi.The last step in the process is the EPS cutting machine. Mold machine are divided into two main categories Block molds and shape mold machines.Block mold machines create a block of foam - from 3' x 2' x 8' up to 5' x 5' x 24'Block Mold can be done manually or automatically. If manually, once the molding process is done The workers need to open the doors of the mold in order to remove the block from the mold.
