Injection Blow-Molding

As a user of plastic processing machines, you know that keeping equipment running efficiently is critical to decreasing downtime, increasing throughput, and reducing scrap. You need solutions that address these challenges to stay competitive and profitable. Nexthermal Engineering Services can analyze key process areas and identify areas where improvement to efficiency can be made. With our expertise in the plastics industry, we can help you turn a problem process into a profitable program.

Why Use Nexthermal Heating Elements for your Plastic Application?

Decrease cycle time and incease throughput
Improve consistency and product quality
Reduce maintainence costs
Maximize process efficiency with thermal analysis
Lower scrap rates
Decrease down time
Optimize an existing system to process a wider range of plastics

Optimize Your Plastic Manufacturing Process

Nexthermal Engineering services can thermally analyze key process areas to identify where problems may exist. Many times the resolution is relatively easy just by simply identifying and selecting the right heater configuration for your application. Or, it may need thermal analysis to pinpoint the root cause. Either way, the most expensive option is to live with it. If it is a thermal issue, Nexthermal will help you resolve the problem.

When you manufacturing process requires heat, you need a process with the necessary efficiency and effectiveness to fulfill your essential production needs. At Nexthermal, we are your source for highly efficient heating elements designed for an array of industrial applications. We design process-specific heater and assemblies to achieve your plastics manufacturing goals.

The various plastics manufacturing applications we serve include:

Plastic Extrusion

Extracting a heater from brass or aluminum bores has often been difficult in applications such as extrusion, sheet extrusion, lip dies, screen changers, and profiled extrusion. The reliable anti-seize cartridges we offer are designed for much easier removal. They are ideal for the most difficult plastic extrusion applications.

Injection Molding Hot Runner Systems

At Nexthermal, we possess wide-ranging thermal profiling experience in the injection molding industry. The coil heaters we offer deliver top-grade performance when designed specifically for your injection molding nozzle. Optimal heat transfer is provided with our Nextflex flexible tubular heaters. These include easy, fast installation in manifolds.

Thermoforming

At Nexthermal, we offer an array of heaters engineered to enhance the thermoforming process, featuring our Nextflex flexible tubular heaters, coil heaters, cartridge heaters, and Elstein infrared radiators.

Packaging

OEM and end-user packaging applications make use of Nexthermal coil heaters and cartridge heaters. We have relationships with various OEM packaging companies to optimize heat profiles on packaging jaws for optimum speed and seal. For applications involving high moisture and movement, Nexthermal heaters are a perfect solution.

Additive Manufacturing

When the range of temperatures vary between filaments, 3D printers make use of heaters that can absorb these temperature variants with tight thermal profiling. At Nexthermal, we offer ideal cartridge and coil heaters for various applications that include nozzle assemblies designed for the increasing challenges of additive manufacturers and 3D printers.
