An effective thermal paper slitting machine gadget is an automatic tail cutter and gluer.
It may trim the surplus paper at the end of the thermal paper roll (the tail) and glue it together to prevent it from unraveling. You don’t have to worry about the tail being too long or too short with this gadget since it will automatically adapt to your requirements.
Overlapping is a frequent problem in thermal paper slitting machines. Overlapping will create printing and cutting issues, reducing the efficiency of the whole manufacturing process.

CFRT Hot Melt UD Prepreg Machine
Continuous fiber reinforced thermoplastic uni-directional prepreg tape (CFRTP) has been widely used in the industrial field due to its excellent mechanical properties and good designability and has been transformed from secondary structural parts to main load-bearing parts.
The hot melt ud prepreg machine impregnation process is one of the main methods for preparing thermoplastic UD tape sheets.
Continuous glass fiber reinforced thermoplastic composite sheet (CFRT) is a new type of composite material with high strength, high rigidity, and high toughness manufactured by a special impregnation process with continuous glass fiber as the reinforcing material and thermoplastic resin (PP, PE, PA) as the matrix. Material.
The hot melt prepreg method is to heat and melt the resin first, and the fiber is impregnated through the molten resin.
This is the most commonly used method without solvent pollution and is especially suitable for preparing prepreg tapes with crystalline resins.
As early as 1972, PPG of the United States adopted this technology to produce continuous glass fiber mat reinforced polypropylene composite materials.
Specifically, two layers of glass fiber precursor needle felt are sandwiched between three layers of polypropylene, and the middle layer is molten resin extruded by an extruder.
The upper and lower layers of resin can be extruded by an extruder or direct resin film is used; this sandwich structure is thermocompressed above the melting temperature of the resin matrix.
Hot melt prepreg machine working process
The continuous fiber is extracted from the fiberglass roving creel, passes through the tension adjustment device, the preheating device, and the tow spreading device, and then obtains the preheated continuous fiber tape, and the screw extrudes the main machine to attach the molten resin to the glass fiber, and then enter the infiltration sheet mold for infiltration, enter the forming calendar to set the shape, and then pass through the roller.
With the arrival of the upsurge of thermoplastic prepreg tapes, there are currently a large number of applications in the fields of military and national defense, aerospace, medical equipment, automotive lightweight, rail transit, and industrial equipment.
Continuous glass fiber reinforced polypropylene prepreg tape UD prepreg machine process
The preparation of continuous glass fiber reinforced polypropylene (GF/PP) thermoplastic prepreg tapes is also the same as the hot melt impregnation method.
Continuous glass fiber reinforced thermoplastic prepreg tape not only has the high strength and modulus of continuous glass fiber but also has excellent impact toughness and recyclability of thermoplastic resin, making it more and more widely used in the fields of automobiles, construction, engineering equipment, etc.
Usually, the continuous glass fiber prepreg tape is processed on a thermoplastic tape, and the thermoplastic tape needs to be tightened during processing to facilitate processing.
Because the fibers in CFRT are continuous, the resin impregnates the fiber monofilaments more thoroughly than conventional thermoplastic composites (such as GMT, LFT).
Therefore, its mechanical properties, especially tensile and bending, and impact are also much higher than those mentioned above in thermoplastic composite materials.

Thermoset and thermoplastic materials are two distinct categories of polymers that are widely used in various industries.
While they may seem similar, there are significant differences between them in terms of their properties and applications.
In this article, we will discuss the key differences between thermoset and thermoplastic materials.
- Definition and Basic Properties
Thermoset materials are cross-linked polymers that, once cured, cannot be melted or reshaped.
They are typically formed by a chemical reaction that creates a three-dimensional network of covalent bonds between polymer chains.
Examples of thermoset materials include epoxies, phenolics, and polyesters.
Thermoplastic materials, on the other hand, are linear or branched polymers that can be melted and reshaped multiple times without any significant chemical change.
They are typically formed by heating and cooling a polymer to a specific temperature range.
Examples of thermoplastic materials include polyethylene, polypropylene, and polycarbonate.
- Properties and Applications
Thermoset materials are known for their high strength, durability, and resistance to heat and chemicals.
They are commonly used in applications that require high-performance materials, such as aerospace, automotive, and electrical industries.
For example, phenolic resins are often used as insulation in electrical components, and epoxies are used as adhesives and coatings in aerospace applications.
Thermoplastic materials, on the other hand, are known for their flexibility, ease of processing, and recyclability.
They are widely used in consumer products, packaging, and automotive industries.
For example, polyethylene is commonly used in plastic bags and containers, and polycarbonate is used in automotive headlights and safety glasses.
- Processing and Recycling
Thermoset materials are typically processed through a curing process that involves heat or chemical reactions.
Once cured, they cannot be melted or reshaped, which makes recycling difficult.
Thermoplastic materials, on the other hand, can be melted and reshaped multiple times without any significant chemical change, which makes them easier to process and recycle.
They can be melted and molded into new products, which reduces waste and conserves resources.
Polypropylene honeycomb is a lightweight and strong material that has been gaining popularity in various industries.
It is made up of hexagonal cells that are connected by thin walls, forming a strong and rigid structure.
This material has excellent strength-to-weight ratio and is highly resistant to moisture, chemicals, and UV radiation.
