High Grade Tunnel Dryer Machine in Bangladesh — Continuous Ink Curing

Machine Specification

Why curing temperature is not negotiable

Plastisol and most textile inks only become permanent once the whole ink film reaches its cure temperature — typically around 160°C for plastisol. Under-cured prints look fine leaving the factory and then crack or wash out within a few launderings. For an export order, that is a buyer complaint and often a chargeback, discovered long after the shipment has left.

A tunnel dryer removes the guesswork by holding a controlled temperature and a set belt speed, so every garment receives the same dwell at the same heat. The high-grade specification matters at volume: a wider belt and better-distributed heating mean the dryer keeps pace with an automatic press instead of becoming the bottleneck at the end of the line.

Applications

Garment printing factories use high-grade tunnel dryers as the curing stage at the end of automatic and semi-automatic press lines. Export-focused operations depend on them because buyer wash-fastness standards are only met with properly cured ink. Larger workshops also use them for curing DTF transfers and heat-applied finishes.

The dryer is the natural companion to our High-Speed Oval Screen Printing Machine and Round Shape Automatic Screen Printing Machine — the press sets throughput and the dryer must match it. For lower volumes, our Ordinary Tunnel Drying Machine covers the same function at lower capacity and cost.

Frequently Asked Questions

What temperature does plastisol ink need to cure?

The full ink film typically needs to reach around 160°C. Belt speed and chamber temperature together determine whether it does. Operator training covers how to verify cure with a temperature probe rather than assuming.

How is this different from the Ordinary Tunnel Drying Machine you also sell?

This high-grade model has a wider belt, higher heater capacity and better heat distribution, so it sustains higher throughput. The ordinary model does the same job at lower capacity and lower cost, suiting smaller workshops.

What belt width is available?

Up to 800mm on the standard configuration, which handles garments and larger printed pieces. Confirm your maximum item width with our sales team before ordering.

How do I check that prints are properly cured?

Use a temperature probe or heat-sensitive strip to confirm the ink film reaches cure temperature, and wash-test samples from early production. Operator training covers both methods.

What is the electricity consumption?

It depends on belt width, chamber length and operating temperature. The full rating is supplied with the quotation so you can plan the supply and estimate running cost.

What is the delivery and installation timeline?

30–45 days from order confirmation to Chittagong port, plus 7–10 days for inland transport, installation, electrical connection and operator training.
