EPS Hot Melter Machine
Qinfeng's foam hot melt machine is a high-efficiency industrial equipment designed for foam material processing, mainly used for cutting, molding and bonding of foam. Its core function is to melt the surface of the foam material by high-temperature heating, and then bond it to other materials or itself by pressure to form a stable connection. This equipment is widely used in packaging, construction, automotive interior, sporting goods, aerospace and other fields, especially for the processing of thermoplastic foam materials such as EPS, EPP, EPP and XPS.
Its working principle is based on the coordinated operation of the screw's rotation and the heating system. When the waste foam enters the machine from the feed inlet, it is first broken into small pieces by the crushing device, and then these small pieces of foam enter the plasticizing area composed of the screw and the barrel.
The screw is made of high-strength alloy steel. During the rotation process, on the one hand, the foam is mechanically squeezed, and on the other hand, the heating system outside the barrel heats the foam, so that the foam gradually softens and melts under the joint action of mechanical force and thermal energy, and then plasticizes into a uniform melt. As the screw continues to rotate, the melt is continuously pushed to the discharge port and eventually extruded into lumps, which is convenient for subsequent transportation and sales.
Qinfeng has different models of foam hot melter machines: CF-HM100 EPS Hot Melting Machine, CF-HM200 EPS Hot Melting Machine, CF-HM400 EPS Hot Melting Machine, CF-NHM400 EPS Hot Melting Machine, EPS Hot Melting Recycling Line.

Applicable materials
CF-HM100 EPS Hot Melting Machine
The CF-HM100 EPS hot melt machine is designed for processing EPS, EPP, EPE foam waste (such as food trays, cups, small boxes), and is built by Qinfeng Machinery. It is suitable for small spaces and small capacity requirements. The special low hopper is leak-proof and easy to feed. The crusher breaks the material into small pieces and drops them into the barrel, which are extruded by the screw and melted by two ceramic heaters.
The melted material forms a cubic EPS block with a density of 500-600kg/m³, and a single container can carry more than 20 tons. This small hot melt machine is suitable for supermarkets, seafood markets, hotels, etc., so that customers can collect and sell materials conveniently.
CF-HM200 EPS Hot Melting Machine
CF-HM200 EPS hot melt machine is designed for medium-sized waste recycling. It can process EPS, EPP, and EPE materials, and reduce waste by 80%-90%. The semi-enclosed hopper prevents powder leakage and can be opened and closed manually. An air filter can be installed on the top. The hopper is equipped with a safety switch, which automatically cuts off the power when opened to ensure safety.
Double-shaft crusher, one shaft has 9 sets of blades, and the other shaft has 10 sets of blades, which are staggered to effectively catch the falling materials. The bottom screen filters the materials. Suitable for medium-sized recycling centers or seafood markets, the feed inlet height is moderate and easy to operate. CF-HM200 can process a variety of foam materials such as foam boxes and foam boards.
CF-HM400 EPS Hot Melting Machine
The CF-HM400 EPS hot melt machine is designed for large-scale waste recycling. It has a processing capacity of 150-200kg/h and is suitable for EPS, XPS, EPP, and EPE materials. The waste volume reduction can reach 80%-90%.
The crusher adopts a four-axis design. The two sets of axes are equipped with 10 and 11 sets of staggered blades respectively, which effectively grab and force the material into the barrel, and the bottom screen filters the material. The final product is a foam block that can be sold directly or further processed. The material density is 500-600kg/m³, and a 40-foot container can load more than 20 tons.
EPS Hot Melting Recycling Line
EPS hot melt recycling production line (200-250kg/h) is a special equipment for processing EPS foam (such as tableware, packaging, insulation materials), which is converted into EPS recycled particles through crushing, melting, granulation and other processes.
The production line uses a 4-axis crusher, with two axes symmetrically installed with staggered blades, which form a wave-like clamp when rotating to crush the foam. The crushed material is sent to the silo by the fan and then enters the hot melt machine. In the hot melt machine, the material is heated to melt by the screw conveyor, and then cut into blocks by the hydraulic blade for easy storage and transportation.
EPS Hot Melting Machine Advantages
EPS hot melt machines occupy an important position in industrial production with their advantages such as efficient melting, wide applicability, precise temperature control, environmental protection and energy saving, easy operation and maintenance, and high-quality output.
Highest Compression Ratio
This is the biggest advantage of hot-melt machines. By heating, melting, and then extruding, they can compress EPS foam to 1/90th or more of its original volume, significantly reducing storage space and transportation costs.
Easy for Storage and Reprocessing
The hot-melt material forms uniform, dense, and regular blocks or strips. These blocks are air-free and have a high density, making them easier to stack, store, and ship.
Ability to Handle Wet/Contaminated Foam
The high temperatures of the hot-melt process evaporate any remaining moisture. This makes the hot-melt machine particularly suitable for processing foam containing small amounts of water or stains, such as in seafood and fruit and vegetable boxes.

The EPS hot melt machine is an industrial equipment specially used to process EPS and other foam materials. It melts the EPS waste by heating, and then processes it into blocks or other shapes for easy storage, transportation and reuse.
The working principle of the EPS hot melt machine mainly includes three steps: crushing, heating and melting, and molding. First, the EPS waste is crushed into small pieces by a crusher. Then, these small pieces of material are fed into the heating cylinder and heated and melted under the push of the screw. Finally, the molten material is extruded and formed into blocks or other desired shapes through a mold.
Styrofoam densifier are widely used in the field of waste plastic recycling and regeneration, and are particularly suitable for scenarios that process large amounts of EPS waste, such as large recycling processing centers, supermarkets, seafood markets, hotels, etc. In addition, it can also be used to produce EPS foam blocks, insulation boards and other products.
Yes, the EPS blocks after hot melting can be stacked. EPS (Expanded Polystyrene) blocks, after undergoing the hot melting process, can be molded into a more compact and stable form, which allows them to be stacked. Stacking these blocks can save space for storage and transportation.
Reduces volume: Significantly decreases storage and transportation costs.
Eco-friendly: Prevents EPS waste from ending up in landfills or oceans.
Cost-effective: Lowers disposal fees and creates recyclable material.
Efficient: Converts bulky waste into manageable, stackable blocks for easy recycling.
