[China Aluminum Industry Network] The aluminum alloy's heat dissipation and good appearance performance has surpassed the current plastic materials, plus the weight of its own weight is plastic can not be replaced.
1. The difference in materials: Die-casting aluminum alloy generally uses ADC12 or ALsi9cu3. Two-car aluminum generally adopts 6063 or 6061.
2. The difference in appearance: Die-cast aluminum is equivalent to the plastic injection molding process, can create any shape, the shell above the street lamp is generally die-cast aluminum. The shape of the equal cross section adopted by the two-vehicle aluminum has little change, such as the heat sink of the bulb lamp and the aluminum profile of the door and window.
3. Thermal conductivity: The general conductivity of die-cast aluminum is about 80-90W/MK, while the thermal conductivity of car aluminum is about 180-190W/MK.
4. Cost: The cost of die castings and car aluminum is relative, both calculated by weight and machining. Calculate costs based on real-time material prices and manual calculations. Relatively speaking, the cost of die-casting aluminum is higher, but the specific situation should be analyzed.
5. Production efficiency: The production efficiency of injection molding is certainly higher, and the batch production is generally more than 1,000 in a day, and the dimensional stability is stable. The shrinkage rate is 0.5%. The composition of the car aluminum machining more, as the name suggests is the car aluminum. The efficiency is naturally lower.
6. Application: Die-cast aluminum is widely used in automobiles, street lamps and the current mobile phone industry. Aluminum cars are widely used in downlights, ceiling lights, and doors and windows.
Guide Ring is a mechanical seal, also known as a guide ring. It is usually made of metal or plastic and used to support and position pistons or rods. Guide Ring has excellent wear resistance and corrosion resistance, which can effectively reduce leakage and friction, thereby extending equipment life. Guide Ring is widely used in the hydraulic, pneumatic, mechanical, and automotive industries as an important mechanical seal.
The classification of Guide Ring can be divided by material, structure, and purpose. According to material classification, Guide Rings are mainly divided into metal Guide Rings and plastic Guide Rings. Metal Guide Rings are usually made of metals such as copper, iron, and stainless steel, which have high strength, wear resistance, and high-temperature resistance; The plastic Guide Ring is usually made of polytetrafluoroethylene (PTFE), nylon, polyimide and other materials, with good corrosion resistance and low friction coefficient.
According to structural classification, Guide Rings are mainly divided into unidirectional Guide Rings and bidirectional Guide Rings. A unidirectional guide ring can only withstand pressure in one direction and is typically used in hydraulic and pneumatic systems; The bidirectional guide ring can withstand bidirectional pressure and is typically used in the mechanical and automotive industries.
According to usage classification, Guide Rings are mainly divided into piston Guide Rings and rod Guide Rings. The piston guide ring is usually used to support and position the piston, preventing friction and leakage between the piston and the cylinder liner; The rod guide ring is used to support and position the rod, preventing friction and leakage between the rod and the seal.
