Plastic Annealing Oven

Introduction

Kerone provides advanced plastic annealing oven engineered to deliver precision, reliability, and high operational efficiency. With 50+ years of multidisciplinary engineering expertise, Kerone designs fully customized systems tailored to industrial heating, drying, thermal processing, and laboratory standards.
We design, Manufacture, supply and install plastic annealing heating system that heats the plastic at specified rate till it achieves uniform Annealing temperature through entire surface of plastic material, once the annealing temperature is achieved plastic annealing heater maintains the annealing temperature for specified time duration based on the type of plastic under process, later cooling down the plastic at fixed to achieve to achieve the ambient temperature.

Why Choose Kerone Plastic Annealing Oven

Kerone’s Plastic Annealing Ovens are specifically designed with the thermal sensitivity of plastics in mind, featuring gentle forced convection to prevent surface marking, tight temperature uniformity of ±2°C or better, and fully programmable ramp-and-soak controllers that manage the critical heating and cooling rates needed for effective stress relief. Kerone’s engineers work closely with clients to develop the optimal annealing cycle for each specific plastic material — whether acrylic, polycarbonate, nylon, PTFE, or PEEK, ensuring consistent results and maximum product quality.
Annealing is Process to heating plastic to particular temperature where it soften and becomes free flow, Placed in mold for taking shape, later slowly cooling down. Plastic annealing process helps in reducing the stress with in plastic and makes it more rugged, better finished product, suitable for the high strength applications

Types and Features of Plastic Annealing Oven

Kerone offers Plastic Annealing Ovens in both batch and continuous configurations. Batch models range from small bench-top units for prototype work to large walk-in chambers for production volumes. Continuous tunnel ovens with conveyor systems are available for high-volume applications. All models feature programmable multi-ramp controllers, forced air recirculation with adjustable speed, and stainless steel interiors for contamination-free processing.

KERONE specializes in the manufacturing of various types of Plastic Annealing Heaters, designed to meet diverse industrial requirements with precision temperature control and reliable performance.

Batch Type Plastic Annealing Heater

Batch plastic annealing heaters are the most commonly used systems for annealing applications. These units are equipped with doors for loading and unloading trays or racks, after which the material is heated at a controlled rate. Batch systems are also available in multi-stack configurations to accommodate multiple trays simultaneously. However, as a non-continuous process, they require longer annealing cycles due to restricted airflow and batch-wise operation.

Conveyorized Plastic Annealing Heater

Conveyorized plastic annealing heaters operate on a continuous process principle. Plastic components are placed on a conveyor belt that moves through a tunnel-like oven equipped with a customized heating arrangement. This continuous system significantly reduces annealing time compared to batch ovens and is highly suitable for large-scale industrial production due to its efficiency and automation compatibility.

Infrared Plastic Annealing Heater

Infrared plastic annealing heaters are continuous ovens that use infrared radiation as the primary heat source. Plastic parts absorb energy transmitted through infrared waves, enabling rapid and efficient heating. This method accelerates the annealing process while maintaining precise temperature control and improved product quality.
