Why does pc material crack after injection molding
PC material cracks after injection moldingWhat is the reason for PC board curling?are two main reasons forWhat is the reason for PC board curling?: Poor strength and toughness and stress not completely released. PC (polycarbonate) materials with poor strength and toughness have excellent physical and mechanical propertiesWhat is the reason for PC board curling?, such as high impact resistance, tensile strength, bending strength, and compression strengthWhat is the reason for PC board curling?, but under certain conditionsWhat is the reason for PC board curling?, such as improper injection molding process, unreasonable raw material formulation or defects in the material itself, its strength and toughness may be reduced.
There are two main reasons why PC materials crack after injection molding: one is that the strength and toughness of the material itself is not good, and the other is that the stress generated during the injection molding process is not completely released.
There are two main reasons why PC materials crack after injection molding: poor strength and toughness: Although the PC material itself has excellent physical and mechanical properties, such as impact resistance, tensile strength, bending strength, etc., if the material is improperly formulated or injection molding process The parameter setting is unreasonable may lead to a decrease in the strength and toughness of the product, which may easily cause cracks to appear when stressed.
There are two main reasons why PC materials crack after injection molding: poor strength and toughness: Although the PC material itself has excellent physical and mechanical properties, including impact resistance, tensile strength, bending strength, etc., if the process parameters during the injection molding process are improperly set, such as inaccurate control of injection pressure, temperature, time, etc., may lead to a decrease in the strength and toughness of the product, resulting in cracking during subsequent use.
There are two main reasons why PC materials crack after injection molding: poor strength and toughness: Although the PC material itself has excellent physical and mechanical properties, including impact resistance, tensile strength, bending strength, etc., if the material formulation or injection molding process is improper, it may lead to poor strength and toughness of the product, which may easily cause cracks to appear after injection molding.
What is the reason for pc product cracking
1. Cracking of PC products is mainly caused by internal stress in materials, environmental erosion, structural design defects and external impact. Internal stress problem Residual stress during the molding process: Uneven cooling during injection molding will cause internal stress to accumulate. For example, products with large differences in wall thicknesses have different cooling rates at the junction of thickness, which is prone to crack germination points. New stress is caused by processing: If the parameters of post-processing such as drilling and cutting are inappropriate, the balance of the material structure may be destroyed.
2. Cracking of PC materials may be caused by a variety of reasons. Processing factors During the processing process, if PC materials are subjected to excessive temperatures or long-term heating, their molecular structure will change, resulting in a decline in material properties and prone to cracking. In addition, improper forming processes, such as too fast injection speed and unreasonable mold design, may also cause cracking of PC products.
3. There are two main reasons why PC materials crack after injection molding: poor strength and toughness and insufficient stress release. Poor strength and toughness Although PC (polycarbonate) materials have excellent physical and mechanical properties, such as high impact resistance, tensile strength, bending strength, and compression strength, under certain conditions, such as improper injection molding process, raw material formulation When unreasonable or the material itself has defects, its strength and toughness may decrease.
How to flatten a transparent PC board
The method is as follows: Temperature control: Place the transparent PC board in a high-temperature environment, such as sunlight or hot water, and use the principle of thermal expansion and contraction to gradually flatten the PC board. Heavy object pressing: Place the transparent PC board on a flat desktop, and evenly press its surface with heavy objects (such as books, slabs, etc.) to gradually flatten the PC board. However, it should be noted that heavy objects should not be too heavy, so as not to cause deformation or rupture of the PC board. Stretch and flatten: Stretch the transparent PC board to a flat state, then fix it with a fixture or directly dry it.
PC board is light and rigid: light in weight, only half of glass and 1/3 of acrylic board. It has good adaptability and safety. It is easy to handle, drill, and cut. It is not easy to break during installation. It is simple and safe to construct. The above details are the most common PC board processing processes. In addition, PC board processing processes include PC board hot pressing, PC board coating, PC board printing, PC board compression molding, blow molding, etc. If you are interested, you can have a further in-depth understanding.
The pc board roof is leveled by heating. Use an electric iron to heat the folding area and press it tightly with glass. Spray some water under the arched position and press it with a heavy object to restore the level.
If the hot water bath method is used, the plate needs to be completely immersed in hot water above 80 ° C, softened, and taken out and pressed to dry. Weight flattening method: For plates with slight bending or wavy deformation. Lay the plate on a flat table, cover it with a protective film, and evenly place heavy objects (such as books, sandbags, etc.), and maintain the pressure for 24-48 hours. Heavy objects need to be evenly distributed to avoid excessive local pressure causing damage to the plate. This method is simple to operate, but you need to ensure that the table is completely flat.
To make a transparent PC board have soft edges, you can achieve it in the following ways: Heating and softening method preparation tool: hot air gun, heat-resistant gloves, flat workbench. Operation steps: Move the hot air gun evenly about 10-15 cm away from the PC board to heat the PC board evenly. When the PC board is heated to a certain extent, it will become soft and plastic. At this time, quickly pinch the edge into the desired soft edge shape with your hand or with the help of a tool.
Heat correction method (for slight bending deformation) 1) Hot water immersion method: Put the deformed PC endurance board in hot water at 60 - 80 ° C and soak it for 10 - 20 minutes, taking care not to let the water temperature be too high, causing the board to discolor or deform more severely. After taking it out, place it on a flat hard surface like wooden board or glass, and press it evenly with a heavy object on the surface of the plate. After it has completely cooled, it will be smooth again.

Will the pc board bend after using it for a long time?
1. It will turn crookedWhat is the reason for PC board curling?of. influenced by the environmentWhat is the reason for PC board curling?, may be cold bent and hot bent. The impact resistance of PC boards allows them to be cold bent at room temperature, or can also be hot bent. The company has large-scale bending machines and oven equipment, which can perform cold bending and hot bending processing of PC boards within 5 meters. The endurance plates are installed into arches, semicircular roofs and windows by cold bending at the construction site according to the design drawings. The minimum bending radius is 100 times the thickness of the plate used.
2. Second, cleaning PC endurance boards can also increase the service life. When cleaning, water below 60 degrees Celsius must be used, because PC endurance boards may deform under high temperatures.
3. The shortcomings of epoxy boards and pc boards are the following. Disadvantages of epoxy board (FR-4): High brittleness: Epoxy board is prone to rupture when subjected to external impact or bending, so its bending performance is poor. Difficult to process: Epoxy board is relatively hard and difficult to process. Usually requires the use of special cutting and drilling tools for production.
4. Antibacterial and mildew proof: PC material itself has excellent weather resistance and chemical stability, has good resistance to bacteria, molds and other microorganisms, and is more suitable for the hygiene requirements of food processing. Environmental protection and safety: PC chopping boards can be recycled and reused, meet environmental protection standards, are non-toxic and harmless, and are safer to use.
5. High strength: High tensile strength and bending strength. size stability: Excellent size stability, not easy to deform. Excellent heat resistance and low temperature resistance: It can maintain stable performance over a wide temperature range. Flame retardant: It has certain flame retardant properties and meets safety standards. Machinability: Easy to process and shape, can meet the needs of different applications.
What's wrong with the oil edge when PC plate is hardened
1. The silicone oil separates from the base glue. The hardened oil edge of pc plate is caused by the separation of silicone oil from the base glue. PC boards are also called polycarbonate boards, polyester boards, and caprones boards. Weak acid resistance is made of polycarbonate as the main component and co-extrusion technology CO-EXTRUSION.
2. When the PC-ABS raw material is oily and causes airflow marks and stress marks on the slider, surface hardening can improve the appearance and wear resistance, but attention should be paid to the issues of binding force and stress changes. Advantages of hardening the surface. After the surface is hardened, the appearance of the slider will be smoother and smoother, and airflow marks and stress traces can be covered up to a certain extent. At the same time, the increase in surface hardness improves wear resistance and extends service life.
3. Thermal correction method (for slight bending deformation) 1) Hot water immersion method: Put the deformed PC endurance board in hot water at 60 - 80 ° C and soak it for 10 - 20 minutes, taking care not to let the water temperature be too high, causing the board to discolor or deform more severely. After taking it out, place it on a flat hard surface like wooden board or glass, and press it evenly with a heavy object on the surface of the plate. After it has completely cooled, it will be smooth again.
