Truck-In Oven
ZonHoo truck-in ovens are heavy-duty, cart-loaded batch ovens for large frames, racks, and assemblies. By rolling full trucks in and out of the chamber, you get safer loading, faster changeovers, and consistent temperature from batch to batch.Line-side preheating stations for tools, molds, and parts – stable start temperature, faster takt time, fewer quality surprises.
Introduction – ZonHoo Truck-In Oven Line
What Is a Truck-In Oven?
A truck-in oven (also called a cart-in batch oven) is a floor-level batch oven where the product is loaded on wheeled trucks instead of being stacked directly on fixed shelves inside the chamber.
Operators:
Load parts on the cart outside the oven
Roll the truck along rails or a flat floor into the truck-in oven
Run the programmed heating cycle
Roll the truck out and move the finished batch to the next station
Compared with a general industrial batch oven, a ZonHoo truck-in oven is optimized for:
Heavy and bulky loads on steel trucks
Repeatable layouts – same truck layout every batch
Safer, faster loading and unloading at floor level
ZonHoo truck-in ovens are cart-loaded batch ovens built around one or two wheeled trucks, so your operators load at floor level, roll the whole batch in, and roll it back out again—no more climbing into a hot chamber or restacking heavy parts by hand. With a few well-chosen options we can balance investment cost, lead time, and performance for most heavy-load jobs, while still tuning the chamber size and airflow to your actual truck layout instead of an empty test box. The circulation system is sized for dense, multi-level racks, giving you quick heat-up and repeatable part-to-part temperature even with frequent door openings, and the reinforced floor, rail zones, and industrial-grade components are built to live with daily cart impacts. For plants dealing with slow changeovers, inconsistent layouts, or awkward, heavy loading, a ZonHoo truck-in oven lets you push more product through the same space and keep quality stable shift after shift.

Truck-In Oven Design Features & Construction
ZonHoo designs each truck-in oven around your trucks, fixtures, and plant layout. The goal is to move full carts in and out quickly while maintaining tight temperature uniformity and safe operation in daily production.
Cart-Loaded Batch Design
- Custom single-truck or dual-truck layouts to match your load size and weight
- Multi-level shelves, hooks, or dedicated fixtures built onto the truck
- Floor or recessed rails designed for your forklifts, tugger trucks, or manual handling
- Hinged, bi-parting, or vertical lift doors selected for your building height and crane access
Airflow & Temperature Uniformity
- Engineered horizontal crossflow or combination airflow tuned to your truck layout
- Recirculation blowers sized for real pressure drop through racks and dense loads
- Typical truck-in oven temperature uniformity of ±3–5 °C at steady state with full load
- Optimized ductwork to avoid hot and cold spots on tall carts and multi-level shelves
Structure, Insulation & Floor Design
- Heavy-gauge steel shell with reinforced door frames and rail zones
- High-performance insulation (typically 100–150 mm) to reduce heat loss and energy cost
- Plate floor, integral rails, or refractory floor depending on load weight and temperature
- Industrial-grade door hardware and seals for long service life
Safety for Coating and Solvent Processes
- Dedicated fresh-air and exhaust design for solvent-bearing coatings and adhesives
- Independent high-limit temperature protection and safety interlocks
- Optional LEL monitoring for critical truck-in oven installations

Truck-In Oven Operating Precautions
To protect operators, product quality, and equipment life, ZonHoo recommends the following precautions when operating a truck-in oven:
Loading & Layout
- Respect the specified maximum truck weight and shelf loading limits
- Keep airflow paths open; avoid blocking ducts with solid plates or over-packed loads
- Use consistent truck layouts to keep truck-in oven uniformity stable from batch to batch
Safety & Maintenance
- Check door seals, rails, and door latches regularly for wear or damage
- Follow process limits for solvents, exhaust settings, and maximum part temperature
- Allow controlled cooling time before opening doors fully to protect operators
- Perform routine checks on fans, heaters, safety switches, and limit circuits
ZonHoo supplies each truck-in oven with operating instructions and a maintenance checklist that can be adapted to your EHS and quality systems.

When is a truck-in oven the right choice?
A truck-in oven is ideal when your loads are heavy, bulky, or already moved on carts between workstations. Rolling a full cart into the chamber improves ergonomics, speeds changeovers, and keeps the part layout repeatable from batch to batch.
How many trucks can one ZonHoo truck-in oven handle?
Most ZonHoo truck-in ovens are designed for one or two trucks per heating chamber. Many customers also use extra trucks outside the oven so the next batch is staged and ready to roll in as soon as the current batch is finished.
Can ZonHoo truck-in ovens handle solvent-based coatings safely?
Yes. For solvent-bearing coatings and adhesives, ZonHoo configures the truck-in oven with the correct fresh-air and exhaust capacity, independent high-limit protection, and optional LEL monitoring to support safe operation.
What temperature uniformity can I expect from a ZonHoo truck-in oven?
For most applications, ZonHoo designs the truck-in oven to achieve approximately ±3–5 °C uniformity at steady state with full load. The exact figure depends on your product geometry, truck layout, and process window.
What is the typical lead time for a truck-in oven?
Typical lead time is around 8–14 weeks depending on chamber size, temperature rating, configuration, and workload. ZonHoo provides a gated plan from design and approval drawings through fabrication, FAT, shipment, and SAT.
What support is available after the truck-in oven is delivered?
ZonHoo offers installation guidance, commissioning support, operator and maintenance training, and spare-parts packages. Optional remote diagnostics help your team keep truck-in oven uptime high.
Truck-In Oven Applications & Industries
ZonHoo truck-in ovens are used wherever large or heavy parts are carried on carts and require controlled heating. Typical applications include:
- Powder coating and wet paint curing for frames, racks, cabinets, and welded assemblies
- Adhesive and bonding curing for automotive, machinery, and fabricated components
- Preheating of molds, dies, and tools prior to casting, forming, or forging
- Stress relieving and tempering of welded and machined parts
- Drying of metal parts, fixtures, and jigs before coating or assembly
- Post-curing of composite parts on dedicated trucks or fixtures
