What Oushida Box Sealing Machines Are Offered Today? Top Models Unveiled!

In packaging operations, reliable box sealing machines are key to efficiency. Oushida provides three high-performance hot melt box sealing machines, each tailored to different needs. Below are their core advantages, working principles, and key specs.

1. OSD-812 Semi-automatic Hot Melt Box Sealing Machine

Advantages:It balances manual control and automation—cuts labor effort vs. full manual sealing, and adapts flexibly to various box sizes. Hot melt tech ensures strong, tamper-resistant seals, perfect for small-to-medium production lines.

Working Principle:Operators place packed boxes on the conveyor. The machine auto-positions boxes, applies hot melt adhesive evenly on sealing edges, and presses flaps to form tight seals. Easy monitoring guarantees consistent quality.

Key Specs:Production speed: 40-60 boxes/min

Packing box specs (LWH mm): (80-300)(70-200)(30-90)

2. OSD-812 Hand Push Hot Melt Box Sealing Machine

Advantages:Compact for tight workshops and suits moderate production. Manual pushing lets operators control the process, ideal for irregular boxes or small batches. Still delivers efficient, consistent sealing.

Working Principle:Operators push boxes along guide rails. As boxes move, the hot melt system activates to apply precise adhesive on flaps. A pressing mechanism secures flaps—simple design means low maintenance.

Key Specs:Production speed: 40-50 boxes/min

Packing box specs (LWH mm): (80-300)(50-200)(20-90)

3. OSD-812 Automatic High Speed Hot Melt Box Sealing Machine

Advantages：High-speed (50-90 boxes/min) for large-scale lines—boosts productivity drastically. Full automation eliminates manual work, reduces errors, and enables 24/7 operation. Handles wider box heights (up to 120mm) with a durable build.

Working Principle：Boxes auto-feed via conveyor. Sensors detect box size and adjust the sealing mechanism. Hot melt adhesive is applied precisely, and boxes are sealed/discharged auto—intelligent control ensures stable high-speed performance.

Key Specs：Production speed: 50-90 boxes/min

Packing box specs (LWH mm): (80-300)(40-200)(20-120)

Oushida’s 812 series meets diverse packaging needs—from flexible semi-auto to space-saving hand-push, or high-speed auto. All deliver reliability and efficiency to boost your operations.
