Introduction to the high-strength connection design of PEM Standard Parts

Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. is a professional hardware company integrating design, R&D, production and sales. We have accumulated rich experience in the manufacture of standard parts and non-standard customized hardware accessories. In particular, the PEM standard parts we produce have been highly recognized by many customers for their high precision and high quality. PEM Standard Parts is one of our products. This is a highly specialized type of fasteners, mainly used for fixing and connecting metal sheets. PEM fasteners were developed by PennEngineering. Its unique design and efficient self-locking characteristics have been widely used in the manufacturing industry. Whether in electronic equipment, communication equipment, or in household appliances, aerospace and automotive industries, PEM fasteners have become the first choice for different industries due to their excellent performance.
PEM standard parts are known for their high-strength connection design, which can be firmly fixed on metal sheets without damaging the material. Its design not only saves installation space, but also has excellent anti-pullout and anti-rotation capabilities, which can provide long-term stability for the equipment.

1. High-strength connection design principle of PEM standard parts
Self-locking fastening principle: One of the characteristics of PEM standard parts is its self-locking fastening principle. This principle is based on the combined effect of mechanical force and friction. During the installation process, PEM fasteners are embedded in the metal sheet through a cold pressing process to form a self-locking structure. This structure can automatically lock when subjected to external force to prevent loosening. Compared with traditional threaded connections or welding processes, the self-locking fastening principle of PEM standard parts simplifies the installation process and significantly improves the strength of the connection.
High-strength pull-out resistance: The high-strength connection design of PEM standard parts enables it to withstand extremely high pull-out forces. During the installation process, PEM fasteners are embedded in the metal sheet through precisely designed teeth or protrusions, allowing a strong mechanical bite between the fastener and the metal plate. This structure can effectively disperse external forces so that the fasteners will not easily fall off or loosen even when subjected to large tensile forces.
Anti-rotation design: Another key design feature of PEM standard parts is their excellent anti-rotation ability. During the installation of the fastener, the PEM fastener is tightly combined with the metal sheet through a special tooth shape or thread to ensure that the fastener will not rotate when subjected to rotational force. This design improves the stability of the fastener and greatly increases the safety of the equipment during operation, especially in high vibration and high pressure environments. This design is particularly important.

2. The advantages of PEM standard parts are as follows.

Simple installation: The installation process of PEM standard parts is relatively simple, and does not require the use of complex processes such as welding and thread processing. During installation, simply press the fastener into the pre-punched hole through a press to form a solid connection. This efficient installation method greatly saves time and reduces labor and equipment costs, especially for large-scale production lines.
High strength and durability: PEM standard parts can provide long-term stable connections and excellent durability due to their high-strength design. Whether in harsh working environments or in scenarios that require frequent maintenance, PEM fasteners can maintain their excellent performance and reduce the cost of equipment maintenance and replacement.
Applicable to a variety of materials and environments: PEM standard parts are suitable for the connection of metal sheets and can be used in combination with a variety of different materials. In addition, PEM standard parts also perform well in extreme environments such as high temperature, high pressure, and high vibration, and have excellent corrosion resistance and wear resistance, so they have been widely used in industries such as aerospace and automobile manufacturing.
Space saving and light weight: Compared with traditional fastening methods, PEM standard parts are more compact in design and can provide efficient connection solutions in limited space. This makes it particularly popular in electronic equipment, small mechanical equipment, and other fields with strict requirements on space and weight.

3. Types and applications of PEM standard parts
Ningbo Haishu Dongxiang Precision Hardware Co., Ltd. provides a variety of PEM standard parts to meet the needs of different industries and application scenarios. The following are several common types and application areas of PEM standard parts:
PEM self-locking nuts: PEM self-locking nuts are a common self-locking fastener that is widely used to fix metal sheets. This type of fastener can provide strong anti-pullout and anti-rotation capabilities, and is usually used in electronic equipment housings, chassis, cabinets, and other scenarios that require high-strength connections.
PEM self-locking studs: PEM self-locking studs are suitable for scenarios where protruding bolts need to be installed on metal sheets. This stud design provides a strong fixation without damaging the thin plate, and is widely used in industries such as communication equipment, home appliances, and automobile manufacturing.
PEM buckle: PEM buckle is a fastener that is very suitable for quick assembly and disassembly. Its design allows installation and disassembly without additional tools, which is very suitable for equipment that requires frequent maintenance. PEM buckles are commonly used in automobiles, home appliances, and consumer electronics.
PEM self-locking screw: PEM self-locking screw is a fastener with self-locking function, which can remain stable and will not loosen when subjected to external forces such as vibration. It is commonly used in fields with extremely high requirements for safety and stability, such as aerospace and automotive industries.
