Product Introduction

Sintering of PLFE products is a critical step in the molding and processing of polytetrafluoroethylene (PTFE) articles, as it brings about fundamental changes in their performance. Variations in process parameters such as sintering temperature and cooling rate directly affect the molecular weight, degree of crystallinity, and porosity of the final product. These three factors, in turn, influence the material’s physical, mechanical, and electrical properties. Moreover, the quality of the sintering process determines the magnitude and distribution of residual stresses within the article; improper control of sintering can lead to warping, deformation, or even cracking. Our company’s HP-series dedicated curing furnaces feature excellent temperature uniformity, a high degree of automation, and stable performance, making them ideal equipment for the sintering of PTFE products.

Performance and Features

·High temperature uniformity:

Customizable imported high-precision 6-channel and 12-channel temperature巡测 recorders can be configured to meet user requirements, providing continuous display and recording of the actual operating temperatures at all measurement points within the furnace.

· High control accuracy:

The temperature control instrumentation employs an intelligent programmable controller capable of multi-segment programming, with PID auto-tuning and SSR solid-state relay combined with a phase-control power regulator to automatically execute the entire sintering process. The tunnel-type sintering furnace features curve-based cooling profiles, with automatic adjustment of the inlet damper opening angle and fully automated exhaust valves at the outlet. The entire furnace operation is centrally controlled by a PLC, ensuring fully automated sintering.
· Stable and reliable quality:

The blower motor, fan blades, and electric heater are all manufactured from high-temperature-resistant materials, enabling 24-hour continuous operation without downtime. The equipment features stable and reliable performance with low noise levels.

· Easy to inspect and maintain:

Fans, electric heaters, and other accessories are fully standardized and modularized according to the specific configuration of each sintering furnace, thereby enabling more accurate fault diagnosis, more convenient and timely component repair, and reduced maintenance costs.

· This equipment is a specially designed, intelligent sintering furnace that delivers exceptionally high uniformity and reliability, tailored to the stringent requirement for uniform temperature distribution within the furnace during the sintering of polytetrafluoroethylene. It is widely used for the pre-sintering, sintering, shaping, and cross-linking of PTFE rods, sheets, tubes, and powders.

· According to user requirements, various heating methods can be selected, including electric heating, oil-fired heating, and gas-fired heating.

· Depending on the dimensions of the cured products and production volume, various manufacturing processes can be employed, including chamber furnaces, rotary furnaces, stainless-steel mesh-belt conveyor ovens, and suspended-chain conveyor ovens. These processes are widely used in industries such as fluoroplastic manufacturing, rubber processing, non-stick cookware production, film and television equipment manufacturing, and valve manufacturing.
