Continuous Ovens for High-Throughput Industrial Production

ZonHoo continuous ovens are engineered for manufacturers that need stable, repeatable heat processes on a moving line – not one batch at a time. A continuous oven combines a heated chamber with a conveyor system so your parts travel through controlled temperature zones at a constant speed. This lets you cure coatings, dry parts, pre-heat components or heat-treat small pieces in a compact footprint while keeping operators away from hot chambers and heavy racks.

What Is a ZonHoo Continuous Oven?

A ZonHoo continuous oven is an industrial thermal system in which parts move through the heated chamber on a conveyor, carrier or overhead track. It is ideal for high-volume, repeatable processes where the line must keep moving.

Continuous processing – Parts enter, heat up and exit without stopping; ideal for 24/7 plants and takt-time driven lines.
Defined temperature zones – Multiple heating, soaking and cooling zones can be set individually for drying, curing or heat treatment.
Flexible conveyor designs – Belt, chain, roller or overhead conveyors, selected for part geometry, weight and cleanliness requirements.
Engineered for integration – Designed to work with washers, coaters, printers, presses and robots for a single continuous production flow.

As a direct continuous oven manufacturer, ZonHoo designs and builds each line around your parts, takt time and available floor space. From compact belt ovens for electronics to large multi-zone conveyor ovens for metal components, we help production teams shorten cycle time, stabilize throughput and reduce manual handling. Our engineering team can integrate the oven with upstream washing, blasting, printing or coating equipment so you get one coordinated continuous process instead of separate islands.

Available Continuous Oven Models

Industrial Conveyor Oven

General-purpose continuous conveyor oven for drying, curing or preheating a wide variety of components. Suited for manufacturers who need a straightforward belt-style oven for constant, moderate line speeds.

Typical temperature range: 80–350°C (176–662°F)
Belt conveyor for trays, fixtures or loose parts
Ideal for parts washing lines, adhesive curing and light heat treatment

Chain Conveyor Ovens

Heavy-duty continuous ovens using chain conveyor systems – including chain-on-edge and indexed chain designs – for bulky or high-mass components. A good fit for automotive and metalworking plants that require robust fixturing and repeatable positioning.

Handles heavy parts, carriers and large fixtures
Suited for thick coatings, mass parts heating and high-load duty cycles
Easily integrated with automatic loading/unloading systems

Overhead Conveyor Ovens

Continuous ovens for parts carried through the chamber on an overhead monorail or power-and-free conveyor. Perfect for paint and powder coating lines where parts must hang freely and remain accessible on all sides.

Keeps floors clear for operators and carts
Eliminates manual turning of parts; ideal for large frames and welded assemblies
Commonly used in finishing lines before or after spray booths

Continuous Sterilizing Oven

Continuous tunnel-type ovens designed for controlled sterilization and depyrogenation processes in pharma, food and medical production. Configured to meet stringent traceability and validation requirements.

Stable, uniform temperature profile across the belt
Options for HEPA filtration, clean-air design and data recording

Infrared Conveyor Oven

Compact continuous ovens that apply infrared (IR) energy directly to parts or coatings for very fast heating. Ideal where line speed and energy efficiency are the main drivers.

Rapid heat-up and short dwell times; excellent for high-speed lines
Available with short-wave, medium-wave or hybrid IR modules
Frequently used for powder gel, ink curing, plastic forming and drying water-based coatings

Multi-Zone Conveyor Ovens

Continuous conveyor ovens divided into multiple independently controlled zones. Designed for complex thermal profiles where parts must see different temperatures or atmospheres along the line.

Individual control of each zone’s temperature, airflow and sometimes atmosphere
Supports staged drying, curing, heat treatment and controlled cooling in one line
Recipe-based PLC control with data logging for audit-ready traceability

Large Conveyor Oven

Extra-wide or extra-long continuous conveyor ovens for panels, sheet materials, large castings or high overall throughput. Built for heavy-duty industrial duty cycles and challenging layouts.

Custom conveyor widths, heights and load capacities
Engineered support structures for heavy fixtures and large panels
Suitable for automotive body components, composite panels, stone slabs and other oversize products

FAQ

When should I choose a continuous oven instead of a batch oven?

A continuous oven is the better choice when your production is driven by a fixed takt time and similar parts repeat all day. If operators are constantly loading and unloading batch ovens or you are running long curing cycles with small variations, a conveyor oven can combine those steps into one stable, high-throughput line.

What information do you need to design the right continuous oven?

We typically ask for part drawings, material and weight, incoming and target temperatures, desired line speed, upstream/downstream equipment and available floor space. With this information, ZonHoo’s engineering team can recommend the proper conveyor type, heating zones and utilities for your plant.

How do you control temperature uniformity along the conveyor?

ZonHoo continuous ovens use tuned airflow patterns, carefully placed recirculation fans and multi-zone controls. Each zone is tested with mapping or test parts so we can confirm temperature uniformity at different line speeds before the oven ships.

Can a continuous oven handle different products on the same line?

Yes. By using recipe management, adjustable line speed and fixtures or carriers, one conveyor oven can run several product families. During the design phase we work with your production team to define the worst-case load and the needed flexibility.

What about installation, start-up and after-sales service?

ZonHoo provides installation guidance or on-site supervision, start-up and operator training. Our service team supports spare parts, troubleshooting and long-term maintenance so your continuous oven line keeps running with high uptime.
