18-Stations Roll Reducing Machine
Product introduction
As a manufacturer of heating element equipment with 15 years of production experience, Davinvi's engineering team has been dedicated to developing heating element production equipment.
The 18-Stations Roll Reducing Machine is mainly used to reduce the diameter of the heating tube. It softens the tube by heating and uses 18 set of alloy wheels or steel wheels with precise speed synchronization to perform progressive compression.
As the tube diameter is reduced, it applies a uniform, high static pressure from the outside, thereby effectively compacting the magnesium oxide (MgO) powder in the tube to a very high density. Finally, as the tube diameter is reduced, the density of the magnesium oxide powder increases, which in turn changes the resistance of the heating wire and affects the power and thermal conductivity of the heating tube.
Application
such as rice cooker heating tube, kettle heating tube, water heater heating tube, iron heating tube, hot runner tube, air flyer heating tube, cartridge heater
Metal outer tube (usually stainless steel 304, 316, 316L, Inconel 600, copper, aluminum, etc.) + tightly filled MgO powder inside + central resistance heating wire

Product Advantage
1. The 18-station roll reducing machine main body uses an integrated casting molding structure, with small distortion, high precision, and lasting.
2. The speed rate of each pair of axis wheels will increase while the diameter of the pipe is reduced. The details have good linear characteristics and are slightly distorted after pipe shrinkage and elongation, saving materials.
3. When adjusting the roller compression ratio, the roller high center remains unchanged.
4. High geometric precision of the compressed pipe, ovality at<0.05.
5 . Motor with overload protection, when blocked, automatically stops.
6. Speed of pipe shrinking 18m/min. high efficiency.
Initial and final diameter of the tube (including wall thickness).
Tube length: A suitable heating element shrinking machine can be recommended based on the customer's tube length.
Tube material: Stainless steel, carbon steel, copper, aluminum.
Power supply specifications (e.g., single-phase 380V 50Hz).
Recommended roller material: 18-station tube reducing machine with tungsten carbide or steel roller.
Tube applications: Heating elements for air fryers, kettles, electric stoves, etc.
Frequently Asked Questions (FAQ)
Q: Is the 18-station machine more expensive than the one with fewer stations?
A: Yes, but the significantly reduced scrap rate and higher product yield usually allow you to recoup the extra cost within 6-12 months.
Q: Can it process stainless steel tubes?
A: Yes. We recommend using alloy wheels for processing stainless steel heating elements. Alloy wheels are more wear-resistant and extend the equipment's lifespan.
Q: How long does it take to change the mold?
A: Due to the use of 18 sets of progressive tube shrinking wheels, the diameter reduction values are different for each set. It is not recommended for inexperienced engineers to change the mold themselves. Skilled operators can complete mold changes and equipment debugging in approximately 5-6 hours.
Q: Can this machine be integrated into an automated production line?
A: Yes. This machine can automatically feed materials via a feeder, eliminating the need for manual feeding and achieving automatic loading and unloading of heating elements.
