Press Plate

AISI 304/ 410/ 633 stainless steel press plate, the main size is 4'X8', 4'X9', 4'X10', 6'X8', 6'X9', 6'X12', 7'X9', 7'X12'.

Product Description

Stainless steel press plate installation, pretreatment and use

1. The new press template used for the first time should be cleaned with a clean gauze, washed with hot water diluted detergent, washed, wiped, and dried. When installing, follow the first step on the cushion. Put on the template, then lay down the cushion, install the order of the template. There are four things to note in the installation:

1). There is a card type slot on the hanging Gui device to facilitate the adjustment of the position of the template. So as to maintain the shape and flatness of the template;

2). The cushion must be laid flat without deformation;

3). Avoid falling into lubricants and debris during the installation process;

4). If using a tensioning device, consider the expansion factor.

 

2. In order to achieve a complete surface effect of the product, after many years of research and experiments, the design and manufacturing staff of our company proposed that due to the different performances, pressures, and veneer processes of the press, the newly used template must be pre-adapted for adaptability. deal with. After verification, good results have been achieved. Template preprocessing steps:

A. When the template is used, the surface is coated with a release agent or special silicone oil (our company has a special template mold release agent). Under repeated temperature changes, the release agent penetrates through the capillary pores of the template to form a A delicate and sturdy mucous membrane.

B. Spread 1-2 layers of white paper on the working surface of the template, and sandwich 2-4 layers of kraft paper in the middle. Note that unimpregnated base paper is used for the above papers to avoid soiling the surface of the stencil with a resin that is under no pressure.

 

3. Close the hot press, gradually increase the temperature without pressure, 30 °C - 60 °C - 90 °C - 60 °C - 120 °C - 150 °C until the maximum hot pressing temperature. Repeatedly back and forth more than 20 minutes. Then it is naturally cooled, pressurized to 20-30 Kg/cm3, and finally the hot press is turned on so that the surface structure of the template is maintained and smoothed under repeated temperature changes. As a result, a large number of pressing processes can be tolerated in the production process and the surface finish and gloss of the stencil surface do not change. Extend the service life of the template.

 

4. Our company recommends that users who produce laminate flooring and melamine panels use special chrome-plated stencils with high hardness and good durability, because the laminate flooring will directly wear melamine surface materials in a short time press (with Decorative paper with aluminum oxide or transparent surface paper is made by hot pressing and affixing to the surface of a wood-based panel. Therefore, the special chrome plated stencil has the property of reducing friction of aluminum oxide and prolonging the service life of the stencil.

 

Press Plate Storage, Maintenance and Repair

1. Spare or template for long-term storage, wipe the plate with acetone, then apply a layer of release agent evenly on each piece, and stack them neatly in a horizontal manner. And cover the velvet to prevent dust. As far as possible, it should be distributed in a well-ventilated place, especially electroplating stencils. If it is placed in a humid place, the surface of the electroplating layer is likely to come into contact with acidic or alkaline substances in the air, causing moldy spots and affecting the gloss of the stencil.

2. The use of soft light board in addition to the above requirements in addition to the acetone solution in the same direction lightly, can not be used to force rub.

3. In the production process, the plywood has been found to have sticking phenomenon (remove the plate more difficult), the template should be promptly removed, soaked in boiling water to soften the curing glue residue, and then wash with detergent, well coated Professional release agent.

4. Even if the press template is used normally, our company still advises the user to clean the template regularly (a month or two months depending on the output) and apply a special release agent to ensure that no sticking occurs. Once the glued board cannot use the metal tool to remove the veneer, this will damage the template. The only feasible way is to take the template together with the veneer, soak it in hot water for dozens of hours, slowly let the veneer Separate and then use wooden tools to clean up the remaining swarf.

5. Replace the template to be maintained, and clean the resin smudges and residual pieces accumulated on the template in time. When cleaning, the template should be placed on the workbench (high-pressure template should be laid on the surface of the table or a silk cloth), the detergent should be soaked with hot water, the soft cloth should be soaked, and then the stained place should be put again. Point to the decontamination powder, clean and rinse with clean water after drying. Conditional manufacturers can heat the template in a sink or steam cook it. This will soften the resin stains that remain in the template pores, and then follow the above method of cleaning operation, the effect will be better and avoid mechanical cleaning.

6. In the course of use and maintenance, if the template is found to have scratches, wear, plating off and other phenomena, which affect the surface quality of the product, we recommend that the user sent to my company to repair. Because the repair of the stencil has a high degree of professionalism, improper repairs can cause damage to the stencil's structure and cause unnecessary losses.


Use Press Plate To Make Common Problems and Solutions

Problem

Reason

Solution

Sticky Plate

1. The melamine resin formulation is not suitable.

2. The heat press cycle is too short or too long.

3. Curing adhesive in the template pores.

1. Check the dipping test period and reactivity.

2. Adjust the hot pressing process.

3. After heating with hot water, clean with a detergent powder or acetone, dry, and apply a release agent.

Different colors appear on the surface of the press plate

Decrepit ink on decorative paper is transferred on the template

Clean with detergent or detergency powder

Decrease in glossiness of plywood

Resin residue, smudge

Regular cleaning with detergent and detergent

All templates or blue

1. Impregnated water containing excess calcium metal

2. Heat pressure plate heating pipe internal obstruction

1. Cleaning with acetic acid

2. Clean the heat pipe

Chrome layer peels off

1. Mechanical damage

2. Improper installation

3. Corrosion

Send for seat manufacturers to refurbish

Wear and shine around the template (when facing the floor)

Due to the sudden expansion of the long-term substrate board and surface material (including trimerized aluminum), a strong frictional effect is generated, and the well makes the periphery of the substrate in contact with the die plate to generate scratches.

Finish, remove chromium, polish, soft light, re-chrome plating. Must not continue to use, otherwise it will damage the template substrate
