Constant Temperature Vertical Dip Coating Machine

Product Overview

This constant-temperature vertical dip coating system is a millimeter-scale precision instrument developed for liquid-phase thin-film growth in controlled thermal conditions. It combines programmable PLC control, a high-precision stepper motor, and screw-drive lifting to immerse a substrate for a defined period, withdraw it at a controlled speed, and dry it in an integrated constant-temperature oven. The result is a practical workflow for producing films with uniform thickness on sample surfaces.

The equipment is suited to thin-film material preparation in university laboratories, research institutes, and corporate R&D laboratories. Operators can set withdrawal speed, immersion dwell time, baking dwell time, travel, and cycle count to support repeatable experimental procedures. Its compact footprint, straightforward operating interface, and movable format make it appropriate where laboratory space and day-to-day usability are important considerations.

Designed for demanding research work, this unit uses PLC-programmed motion control and a high-precision stepper motor to provide stable lifting and accurate positioning. The integrated oven adds controlled post-withdrawal drying up to +200℃, while PID temperature control and a PT100 sensor support consistent thermal processing. Together, the motion and heating functions provide a controlled basis for repeatable liquid-phase coating trials.

Key Features

• Programmable vertical dip-and-withdraw process: The system controls substrate immersion, dwell, uniform withdrawal, and subsequent constant-temperature drying as a defined coating sequence. Adjustable process values allow researchers to establish procedures appropriate to their liquid-phase film-growth work.

• High-precision stepper-driven lifting: A high-precision stepper motor drives the screw transmission mechanism for stable vertical movement and accurate positioning. This controlled motion supports consistent withdrawal conditions across repeated cycles.

• Adjustable withdrawal speed: Withdrawal speed is selectable from 1~200mm/min in 1mm increments. The fine setting resolution gives operators direct control over one of the central variables in vertical dip coating.

• Defined immersion and baking dwell settings: Immersion dwell time and baking dwell time can each be set from 1~999s in 1S increments. These independent settings allow the liquid-contact and thermal-hold stages to be incorporated into a programmed experimental sequence.

• Integrated constant-temperature oven: The included oven operates from RT room temperature~+200℃ using natural convection. Its 125L internal volume and 500mm×450mm×550mm chamber dimensions provide dedicated space for controlled thermal drying after coating.

• PID thermal control: The oven uses dual-row digital PID temperature control with four-button setting and a PT100 thermocouple. Temperature-control accuracy is ±1.5℃, supporting controlled oven operation within the stated temperature range.

• Clear 4.3-inch touchscreen operation: A 4.3-inch color touchscreen provides a simple, clear control interface for the lifting function. The accessible interface is suitable for users establishing or running research coating procedures.

• Flexible programmed travel and cycling: Lifting travel is adjustable from 1270mm in 1mm increments, with 120 lifting cycles available. Effective immersion depth is ≤200mm, allowing the programmed movement to be matched to the sample and liquid arrangement.

• Substrate and load capability: The equipment accepts sample substrates up to (length)400mm×(width)230mm×(thickness)1~10m and supports a maximum lifting load of ≤5.5kg. These limits provide clear boundaries for configuring sample fixtures and experiments.

• Laboratory-oriented physical design: At 636mm wide, 680mm deep, and 1520mm high, the complete unit includes the constant-temperature oven in a compact vertical arrangement. The approximate complete-system weight is 75kg, supporting placement as a dedicated laboratory process station.
