The vacuum plastic coating process, also known as vacuum metallizing or vacuum deposition, can encounter various challenges and problems during its execution. These issues can impact the quality of the coated products and the efficiency of the manufacturing process. Here are some common problems encountered in the vacuum plastic coating process and their potential solutions:
Pinholes or Porosity in Coating:
Problem: Small holes or pores in the coating can lead to reduced barrier properties and aesthetics.
Solution: Improve the cleanliness of the substrate surface, adjust the coating parameters, and ensure proper degassing of the vacuum chamber to minimize contamination and porosity.
Uneven Coating Thickness:
Problem: Variations in coating thickness across the substrate can result in inconsistent appearance and performance.
Solution: Maintain proper control over deposition rates, substrate rotation or movement, and coating source positioning to ensure uniform deposition.
Adhesion Issues:
Problem: Poor adhesion of the coating to the substrate can result in delamination or flaking.
Solution: Pre-treat the substrate surface with techniques like plasma cleaning or corona treatment to improve adhesion. Ensure proper substrate cleaning and preparation.
Contamination and Impurities:
Problem: Contaminants in the vacuum chamber or on the substrate can lead to defects in the coating.
Solution: Maintain a clean environment within the vacuum chamber, regularly clean the chamber and fixtures, and use high-purity source materials.
Stress and Cracking:
Problem: High residual stress in the coating can lead to cracking or peeling.
Solution: Optimize deposition parameters, such as temperature and deposition rate, to reduce stress. Use stress-relief layers if necessary.
Substrate Warping or Deformation:
Problem: Some plastics may deform or warp under the high vacuum and temperature conditions.
Solution: Choose substrates that are suitable for vacuum coating or implement temperature control methods to minimize substrate distortion.
Phenomenon 1: Bubbling in the groove
Reason analysis:
1. The temperature or pressure does not meet the requirements, resulting in false suction;
2. Insufficient adhesive amount, insufficient spraying amount, or adhesive leakage from the board;
3. Insufficient preheating (softening PVC film) or blistering time (forming time);
4. After vacuum molding, remove the pressure before the temperature drops.
5. The heat resistance of the adhesive itself is not sufficient.
Solution:
1. Increase temperature or vacuum;
2. Increase the amount of glue applied and select high-quality boards;
3. Increase preheating or molding time;
4. After vacuum molding, the temperature should be cooled to room temperature or slightly higher before withdrawing the vacuum.
5. Use with curing agent.
Phenomenon 2: Local blistering
Reason analysis:
1. Uneven glue spraying results in a small amount of local glue, leading to a decrease in bonding strength;
2. The problem with PVC film is that it contains plasticizers, which can easily migrate to the surface during aging or heating, affecting the bonding strength;
3. There is a problem with the heating pipe inside the blister machine, causing uneven temperature.
Solution:
1. Try to ensure a uniform amount of adhesive spraying;
2. Use high-quality PVC film;
3. Timely maintenance of equipment.
Phenomenon 3: Unable to hold or shrink the edge
Reason analysis:
1. When vacuuming, the side temperature is too low or the vacuum degree is insufficient;
2. Insufficient temperature resistance of adhesive;
3. After vacuum molding, remove the pressure before the temperature drops.
Solution:
1. Increase temperature or vacuum;
2. Use with curing agent;
3. After vacuum molding, the temperature should be cooled to room temperature or slightly higher before withdrawing the vacuum.

 

The medium density substrate is processed into various linear shapes and then covered with PVC films of various brightness, colors, and textures, making the products rich and colorful, creating a wide range of choices for consumers. However, the quality of products manufactured using this technology varies greatly. The reasons for these differences are not only due to the factors of the substrate and decorative material PVC itself, but also the control of process parameters during the processing process.

1、 Working principle of membrane press

By utilizing the plasticity of PVC and adjusting and controlling the membrane pressure time, equipment chamber temperature, and air pressure, PVC is heated and pressurized to coat the surface of the workpiece.

2、 The working process of the membrane press

(1) Place the workpiece on the workbench;

(2) The workbench enters directly below the heating plate;

(3) Close the heating plate with the workbench;

(4) The air between the heating plate and the silicone film is extracted, and the silicone film is adsorbed onto the heating plate for heating;

(5) After reaching the set time, compressed air is injected between the heating plate and the silicone film. The silicone film is in close contact with PVC, and the workpiece and PVC are heated. At the same time, PVC is softened, and the temperature at the edge of the plate reaches the activation temperature of the adhesive;

(6) The air between the workbench and PVC is quickly extracted to form a vacuum, and then compressed air is injected between the PVC and the heating plate. PVC is wrapped on the plate under the set pressure and temperature.

A membrane press, also known as a vacuum membrane press or membrane vacuum press, is a machine used in woodworking and the manufacturing of laminated products. It is primarily used to apply decorative or functional laminates, veneers, and films onto various substrates like wood, MDF (Medium-Density Fiberboard), particleboard, and foam. Here’s how a typical membrane press works:

Preparation:

First, the operator prepares the substrate (e.g., a wooden panel or piece) by applying adhesive to it. This adhesive will bond the decorative material or laminate to the substrate when subjected to heat and pressure.

Laying the Decorative Material:

The decorative material, which is typically a flexible PVC or thermoplastic film with a decorative pattern (such as wood grain or solid color), is placed over the adhesive-coated substrate. This material will become the visible surface of the finished product.

Positioning in the Press:

The substrate and decorative material are then placed in the membrane press. The press consists of a chamber or frame with a flexible, heat-resistant membrane or silicone bag suspended above it.

Creating a Seal:

The membrane is lowered to make contact with the decorative material and substrate. It should form a tight seal around the edges to create an airtight chamber.

Vacuum and Heat:

The press is equipped with a vacuum system. When activated, it removes the air from the chamber between the membrane and the substrate. This creates a vacuum or negative pressure inside the chamber.

Heating Elements:

The press also contains heating elements, such as electric heating panels or infrared lamps. These elements generate heat and are positioned above or below the membrane.

Activation:

The vacuum and heat are activated simultaneously. The vacuum draws the flexible membrane tightly around the decorative material and substrate, pressing them together with even pressure. At the same time, the heat activates the adhesive, causing it to bond the decorative material to the substrate.

Curing and Cooling:

The heating elements maintain the desired temperature for the adhesive to cure properly. This curing process may take a few minutes. After curing, the temperature is gradually reduced to allow the bonded materials to cool and set.

Release and Removal:

Once the curing and cooling process is complete, the vacuum is released, and the flexible membrane is lifted. The bonded decorative material is now securely attached to the substrate, conforming to its shape.

Trimming and Finishing:

The finmming and Finishing:ished product, with the decorative material firmly adhered to the substrate, may undergo additional finishing processes such as edge trimming, sanding, or further machining to achieve the desired final dimensions and appearance.

The membrane press ensures a consistent and even application of decorative materials, eliminating wrinkles, air bubbles, and other defects that can occur with manual or less controlled laminating methods. It is widely used in the production of furniture, cabinetry, doors, wall panels, and other laminated products where high-quality surface finishes are essential.

 

How PVC Foil Can Transform Your Kitchen and Bathroom Spaces

It is important to choose the right type of PVC foil to use in your kitchen or bathroom. These products come in different shapes, sizes and designs, but you can easily create a unique look with a few tips.

Peel and stick countertops

Peel and stick countertops are a quick and easy way to update your kitchen or bathroom. These countertop materials are self-adhesive, so they don’t require you to hire a contractor. You can install them in just a few hours, and they come in a variety of colors and styles.

You can also make your bathroom look fancy by installing a bookshelf. You can also try a few more ambitious projects like covering your drywall with a stylish stretch ceiling. The best part about this is that it’s very simple to do.

While you are at it, consider hiding your wires with the drywall or tucking a fan under your cabinet. In fact, a fan can circulate warm air so you won’t have to worry about the pipes freezing over.

6 types of kitchen layouts

Whether you’re renovating or building a new home, you’ll need to know what kind of kitchen layout to choose. Your kitchen layout should be the most functional and efficient. It can help reduce footwork, maximize storage, and keep everything running smoothly.

The working triangle design principle can help you optimize your space. The basic work triangle includes the sink, refrigerator, and stove. However, in smaller spaces, it may not be feasible to follow this rule. In this case, you can consider the one-wall kitchen layout.

These kitchen layouts allow you to place all the major appliances, including the refrigerator, sink, and stove, on one wall. This allows you to open up the rest of your space, and leave three sides of your kitchen free for other uses. You can also add shelving above the base cabinets for extra storage.

If you live in a studio apartment or a small house, a single wall layout might be the best option for you. You can also create a clean, linear aesthetic with this type of design.

For larger homes or open concept spaces, a U-shaped kitchen is a great choice. It offers ample counter space and a comfortable work triangle. A kitchen island is a perfect addition to any U-shaped kitchen.

If you’re looking for a more contemporary design, you can go for a L-shaped kitchen. With this type of kitchen, you have the opportunity to build taller cabinets and make the layout more modern.

When you choose a kitchen layout, you need to consider your family’s needs. If you’re planning to have multiple cooks, a kitchen that is too large could be too crowded. One-wall kitchens are also a good choice for smaller families.

How to install PVC decorative film?

 Substrate adjustment

1. Substrate – Be sure to grind the flat page to a fine and thoroughly touch and insert it thoroughly. If there is oil stains, clean it with solvent.

The temperature of homework is 15 ° C to 20 ° C, and in principle, construction can be carried out at 5 ° C.

 Plane construction

1. The substrate treatment is as described above.

2. Determination of position: The position to be placed first is fixed with leftover materials.

3. Before pasting, peel off the paper by about 10 centimeters, and use a soft cutting blade to gently press the air out from above.

 

4. If there are small bubbles, the blade can be used to puncture them and then the air can be pushed out with a cutting blade. It is best to wrap the cutting blade with a soft and damp cloth to avoid damaging the surface.

Right angle construction

1. Please apply primer to the substrate and dry it thoroughly before smoothing it out

When the flat part is constructed to the right angle part as described above. According to the following figure, the construction can be carried out by gently pressing in the order of the top, or by heating and pressing with an electric hair dryer. At this point, gloves can be worn or a soft cloth can be gently pressed with fingers to achieve good results.

4、 Double right angle construction. The substrate treatment is the same as before.

2. Paste: First, attach A and fold it onto side B, then fold side B onto the quilt and cut off any excess film (note that if the dot printing part of A and B overlaps, it will protrude here. For aesthetic reasons, it is not necessary to fold A to side B).

Construction method for pentagonal and cubic curved surfaces

1. The corners of the substrate should be thoroughly coated with primer (3-4 times), dried, and ground with # 400 sandpaper until smooth and smooth,

2. Use an electric hair dryer to fully heat the corners. When the Polaroid film has appropriate softness, pull it down from the top of Figure 12A and press it down in sequence B’C’D’E ‘.

3. Please pay attention to slowly pulling from the top in the order of Ai B’C’D’E (less than one centimeter at a time), press with your fingers, then move to B “C’D’E and repeat from A to the bottom. Do not be impatient and pull to the bottom at once, which will cause wrinkles and make it difficult to handle.

4. When heating and pulling downwards, it is advisable to extend your fingers deep inside (do not only pull towards the edge; pull and press on one side to achieve good construction results).
