Molded and die cut square liners

1、 Molded square gasket

1. Molding process
   • Compression molding is a manufacturing process that applies pressure to materials through molds to shape them. For square pads, the first step is to choose suitable raw materials. Common materials used for molding square pads include rubber, plastic, etc. For example, rubber molded square pads, during the molding process, rubber raw materials are placed into a specially designed square mold.
   • The design of the mold is crucial. It requires precise control of the size, shape, and surface texture of the square pad. When molding, a certain pressure is applied to the mold by a press machine, causing the rubber to deform inside the mold, filling the space of the mold, and finally forming a square cushion shape.
   • The molding process can achieve efficient mass production and ensure the consistency of square pads. In some application scenarios that require high precision in pad size, such as buffer pads for precision instruments, the molding process is very suitable.
2. Application of Square Cushion
   • In the field of mechanical manufacturing, square pads can be used to reduce wear and vibration between machine components. For example, at the installation site of the engine, square pads can cushion the vibration generated by the engine during operation, protect other components of the machine, and also adjust the assembly clearance between components.
   • In electronic devices, square pads can serve as insulation and cushioning. Like the installation of some circuit boards, if directly installed inside a metal casing, there may be a risk of short circuit due to the conductivity of the metal. Square pads can provide insulation barriers and prevent the circuit board from being damaged by vibration during transportation or equipment operation.
3. Performance Requirement

   • For molded square pads, their hardness needs to be adjusted according to specific application scenarios. If it is used for parts that can withstand high pressure, higher hardness may be required; If it is a pad used for buffering and protecting precision components, it requires lower hardness.

   • Elasticity is also an important performance indicator. Good elasticity can ensure that the pad can return to its original shape after being subjected to pressure, thereby continuously exerting its buffering and supporting effects.

   • In addition, wear resistance and corrosion resistance are also crucial in some application scenarios. For example, square pads in outdoor or chemical equipment need to be able to resist the erosion of environmental factors.

2、 Die cut square gasket

1. Die cutting process
   • Die cutting is the process of cutting materials into specific shapes through molds. For the die-cutting of square liners, the first step is to prepare the raw materials in the form of rolls or sheets. These raw materials can be paper, plastic film, rubber sheets, etc.
   • Die cutting molds are designed based on the size and precision requirements of square liners. During the die-cutting process, the raw materials are placed on the die-cutting machine and cut through the die-cutting die. The shape of the die matches the shape of the square pad, allowing for precise cutting of materials into squares.
   • Die cutting technology is suitable for various types of materials and can achieve cutting of complex shapes. Unlike the molding process, die-cutting mainly involves cutting materials rather than changing their shape.
2. Application of Square Cushion
   • In the packaging industry, square liners can serve as internal support and protective structures for products. For example, in the packaging box of electronic devices, square pads can prevent the device from shaking and colliding during transportation. Paper or plastic square liners made using die-cutting technology have relatively low costs and can meet basic protection needs.
   • Square padding is also used in furniture manufacturing. For example, die cut square pads can be pasted at the bottom of drawers or inside cabinet doors to provide cushioning and reduce noise.
3. Performance Requirement

   • Dimensional accuracy is a key requirement for die-cutting square liners. Especially in applications that require high assembly accuracy, such as electronic product packaging, the size of square pads must be precise to ensure a good match with the product and packaging box.

   • The strength of the material is also a factor that needs to be considered. For some square cushions that require a certain amount of pressure or friction, such as cushions in furniture, the material needs to have sufficient strength to prevent cracking or deformation during use.

   • If it is in special application scenarios such as food packaging, the material of square liners also needs to meet food safety standards and have characteristics such as non-toxic and odorless.
