Frequently Asked Questions (FAQs)
What materials are commonly used to make flat O-rings in Chinese factories?
Flat O-rings in Chinese factories are often made from a variety of materials, including Nitrile (NBR), Ethylene Propylene Diene Monomer (EPDM), Silicone, and Fluorinated rubber (FKM or Viton). These materials are chosen based on their chemical compatibility, temperature resistance, and other factors specific to the application.
What are the typical applications of flat O-rings produced in China?
Flat O-rings are widely used in various industries, including automotive, mechanical, hydraulic, and pneumatic equipment. They are particularly useful in spaces where traditional round O-rings do not fit, such as in rotary sealing applications. They offer a tight seal with less pressure and are known for their longevity and low maintenance.
How are flat O-rings manufactured in Chinese factories?
The manufacturing process for flat O-rings involves several steps. First, the material is selected and extruded into the desired configuration. Then, it is molded using compression, transfer, or injection molding techniques. After molding, excess material (flash) is removed to achieve the perfect shape. For custom sizes, new mold tools are designed and produced using computer-aided design.
What are the advantages of using flat O-rings over traditional round O-rings?
Flat O-rings have several advantages. They require less pressure to create a seal, which can reduce wear and tear on the equipment. They are also easier to replace and can last longer than traditional round O-rings. Additionally, flat O-rings eliminate the need for lubrication, making them a more convenient option for many applications.
How long does it typically take to receive flat O-rings from a Chinese manufacturer?
The delivery time for flat O-rings from Chinese manufacturers can vary but generally ranges from 7 to 15 days. This timeframe includes production, packaging, and shipping. For custom orders or large quantities, the delivery time might be slightly longer, but most manufacturers provide prompt delivery services to meet customer needs.
