Thermoplastic is a polymer resin composition that becomes soft when heated; when cooled, it hardens into desirable products. Thermoplastics are easy to recycle because they don't undergo any chemical property changes when heated or cooled repeatedly.

Introduction to Thermoplastic Molding

In the reversible molding process known as thermoplastic molding, plastic pellets are first melted, then pressed into a mold to take on their final shape, and finally fast-cooled to harden. With a high degree of accuracy and surface polish, thermoplastic injection molding can be utilized to make anything from cell phone cases to car door panels.

Thermoplastic molding is a faster way to make plastic than other techniques because of its extremely high production rate. This indicates that thermoplastic molding is a very economical and effective method of producing plastic, leading to it becoming the industry norm for making plastic components.

Thermoplastic Molding Vs. Thermoset Molding

Thermoplastics and thermosets are both polymer resins, but they differ when exposed to heat. Thermoplastics become soft under heat, while thermosets retain their shape. This causes significant differences between them, mainly in their applications and usage. Moreover, when these materials are used in molding methods, they exhibit differences as follows:

Thermoplastic MoldingThermoset Molding
The cold material is injected into the hot mold.The plastic is first melted and then injected.
It can't be reshaped or re-molded.It can be easily re-molded or reshaped.
This process forms a permanent chemical bond.This process is completely reversible and does not form a chemical bond.
The process does not require high heat or increased pressure.The process requires a significant amount of heat and high pressure.
Thermosets are formed by the phenomenon of condensation polymerization.Thermoplastics are formed through the phenomenon of additional polymerization.
Thermoset injection molding produces: the handles of tools, pool balls, insulation, computer parts, television parts, any electronic equipment, gardening tools, tools, sprockets, and cooking utensils.Thermoplastic injection molding produces: vacuum cleaners, toys, machine screws, gear wheels, kettles, packing film, sacks, power tool casings, toasters, gas pipes, and fittings.

Benefits of Thermoplastic Molding

Following are some of the benefits of thermoplastic molding:

  • High Efficiency: Compared to other techniques, this procedure is exceptionally quick, and the high output rate makes it even more effective and economical. The amount of time between cycles depends on the intricacy and size of the mold, but it often takes only 15 to 120 seconds.
  • Complex Part Production: Thermoplastic molding produces millions of extremely complicated pieces, nearly identical, consistent, and extremely complicated pieces.
  • Cost Efficient Method: In comparison to other methods of molding, labor expenses for thermoplastic molding are often inexpensive. Its cost-effectiveness is aided by the parts' capacity to be produced at a high level and production rate.
