The Difference Between Hand-made Sandwich Panels and Machine-made Sandwich Panels

As is well known, gas purification panels are widely used in clean engineering industries with strict indoor air regulations, such as electronic devices, pharmaceuticals, food, biology, aerospace, instrument manufacturing, and scientific research. However, there are still some users who are not very clear about the purification board, only knowing about the purification board, but not knowing the difference between manual purification board and mechanism purification board. Manual purification board is made by cutting and bending steel coils through a forming machine, and then using a keel forming machine to form the frame keel, and then using galvanized corner pieces to form four frames. The inner side of the clean room sandwich panel is evenly coated with glue, filled with core material, and finally pressed together.

Machine made panels are made by rolling color coated steel plates with edges, applying glue through a glue machine, filling them with core material, and then hot pressing and laminating them together. The rolled color coated steel plates are then bonded to the core material and cut to a fixed length to obtain the finished product.

Handmade boards can be composed of various combinations of main core materials (such as rock wool, aluminum honeycomb, paper honeycomb, etc.) and auxiliary core materials (such as glass magnesium board, gypsum board, etc.), resulting in a diverse range of product varieties.

The variety of machine-made board products is relatively single, generally only one type of filling material, such as rock wool machine-made board, polyurethane machine-made board, hollow glass magnesium board, etc.

The standard production width dimensions for handmade boards are 1200/1180/1160/980, and non-standard widths can be customized. The length dimensions can be customized according to customer needs.

The common width dimensions for machine-made boards are 1150/950, and non-standard widths can be customized. The length dimensions can be customized according to customer needs.

Handmade board size customization to avoid cutting on the construction site. The gmp wall panels are connected by mid aluminum or male and female ports.

The machine-made board construction site can be cut, and the gmp wall panels are connected with tongue and groove joints.

The handmade board is composed of galvanized frame keels around the edges, and the board has high strength; According to different core materials, testing reports of different durations can be issued.

The two long sides of the machine-made board are folded with galvanized frames and sealed with C-shaped edges, while the two short sides are cut with saw blades. The strength of the board is weaker than that of handmade board; But the fire rating of the mechanical board is not sufficient.

In actual installation, we may also encounter situations where the drawings do not match the actual dimensions. Handmade boards can also be cut appropriately to meet the needs of different sizes.
