Medical Device Preheating and Curing Tunnel Furnace

The medical device preheating and curing tunnel furnace is a high-precision and intelligent continuous thermal processing equipment specially designed for the medical device manufacturing industry.This equipment is widely used for adhesive curing, coating drying, and preheating before dispensing processes of products such as syringes, infusion tubes, endoscopes, catheters, connectors, and electronic medical components.It adopts modern microcomputer control technology and features a Class 100 cleanliness design (with a 304 stainless steel inner chamber). It can perfectly integrate into the strict production environments of medical workshops requiring low dust levels, sterile conditions, and high temperature uniformity.

Product Applications

UV/Thermal Adhesive Curing:

Used for rapid and deep curing of medical-grade epoxy resin, UV adhesive, silicone adhesive, and other bonding materials.

Surface Coating Drying:

Used for precise drying and crystallization of hydrophilic coatings and antibacterial coatings on catheter and needle surfaces.

Preheating Treatment Before Assembly:

Used for thermal expansion adjustment and stress elimination of polymer material components before assembly.

Precision Baking of Components:

Used for dust-free moisture removal and baking of medical-grade sensors, PCB circuit boards, and electronic components.

Product Parameters

Product Features

High Cleanliness:

The interior adopts a fully welded structure and is equipped with high-temperature resistant high-efficiency particulate air filters (HEPA), preventing contamination of medical products caused by insulation material shedding or external air entering the chamber.

Precise Temperature Control:

The equipment adopts multi-zone independent PLC intelligent control and high-precision SSR solid-state relay output, providing rapid temperature rise and minimal temperature fluctuation.

Stable Hot Air Circulation:

The specially designed air circulation duct system enables horizontal or vertical airflow circulation, ensuring high temperature consistency at every point inside the tunnel furnace.

Energy Saving:

The equipment uses high-quality high-density aluminum silicate fiber insulation layers. The surface temperature of the chamber remains low, greatly reducing heat loss.

Multiple Safety Protections:

The equipment is equipped with over-temperature alarms, conveyor belt breakage warnings, leakage protection, and fault text display functions through the human-machine interface (HMI).

FAQ

Q1: What cleanliness level can this tunnel furnace achieve? Does it meet medical GMP workshop requirements?

A1: Yes. The equipment uses a medical-grade 304 stainless steel inner chamber, combined with a closed-loop air duct system and high-temperature resistant high-efficiency particulate air filters. The internal working area can reach Class 100/Class 1000 cleanliness standards, fully complying with the requirements of controlled medical device GMP workshops.

Q2: How does the equipment ensure temperature consistency when curing different batches of medical products?

A2: The system uses a PLC programmable controller combined with a human-machine interface (HMI), which can store dozens of sets of process parameters, including temperature and conveyor speed. Meanwhile, the furnace is divided into multiple independent temperature zones with separate temperature control, ensuring that products obtain standardized and repeatable thermal response curves during the preheating zone, constant temperature zone, and cooling zone.

Q3: Can the conveyor belt speed be adjusted? Will it damage small medical catheters?

A3: Yes. The conveyor speed adopts variable frequency stepless speed regulation and can be finely adjusted between 0.1 and 5 meters/minute. For small and fragile medical catheters, we provide Teflon mesh belts or low-friction high-temperature resistant silicone belts, ensuring stable transportation without vibration, scratching, or deformation.

Q4: What safety protection measures are provided when over-temperature or other equipment failures occur?

A4: The equipment is equipped with dual over-temperature protection. Once any temperature zone exceeds the preset threshold, the system immediately cuts off the heating power supply and activates the three-color warning lamp and buzzer alarm. It also integrates motor overload protection and an emergency one-button stop function.

Q5: Can the equipment be customized according to our existing medical device production line?

A5: Yes. Due to the wide variety of medical device specifications, we can provide customized designs based on your feeding and discharging height requirements, product dimensions, required curing time, and connection requirements with automatic dispensing production lines, including customized equipment dimensions and power configurations.
