In modern logistics, building partitions, and advertising decoration fields, lightweight and high strength have become core demands. PP hollow sheet reshapes industry standards with exceptional compressive strength, ultra-low thermal conductivity, 100% recyclable eco-features, and honeycomb structure weight reduction design! The unique air interlayer achieves "gram-level load-bearing", increasing strength-to-weight ratio by 180%, while integrating moisture-proof, sound insulation, and thermal insulation – a green pioneer replacing wood and metal sheets.

JWELL Production line introduction

Extruder

JWS120\JWS150 type extruder or add JWS65\JWS90 type for co-extruder.

PP Hollow Sheet Special molds

It can be used as a flange to realize a set of molds to produce a variety of width products; The setting table needs to be adjusted and sealed.

An air knife is installed before entering the setting table to assist cooling.

Setting table

The PP setting table vacuums the surface of the product, the thickness of the setting plate is usually 80mm, the internal water is cooled, the water temperature is within 20°C, the hydraulic control lifting, and the thickness of the product is controlled by the thickness of the cushion block.

Oven

The freshly cooled products are baked at low temperature, so that the stress inside the products is released, and the warping and other phenomena are avoided after the products are completely cooled. The temperature can be adjusted in different areas, and the process of the product can be adjusted according to the actual situation.

Corona device

Since PP hollow lattice board is usually used in the packaging industry, the surface needs to be printed with all kinds of advertisements and slogans, and the paint, ink and plastic surface are not incompatible, so it is necessary to use a corona device to break through the microscopic holes on the surface of the product through discharge, so that the paint and ink are attached to it.

Bellows

The PP hollow lattice plate needs to be cooled sufficiently, and the device is assembled after the oven to cool it.

Shearing machine

PP grating board has a softer texture and usually uses a shearing machine, which is more efficient. When the line speed of the production line is fast and the length of the product is short, the cutting may be untimely when the cross-cutting machine is used.
