Detailed explanation of the seal customization process: from demand analysis to production delivery

Seals play a vital role in various mechanical equipment and systems, ensuring effective sealing of liquids or gases, reducing leakage, and improving equipment performance. However, standardized seals often cannot fully meet the needs of specific applications. Customized seals can be optimized for the special requirements of the equipment to ensure the best sealing effect. This article will elaborate on the complete process of seal customization, from demand analysis to production delivery, to help users understand how to achieve the best performance of the equipment through customized solutions.

1. Demand Analysis and Planning

Collect Basic Information

Application Environment: Determine the environmental conditions in which the seal is located, including temperature range, pressure level, media type, etc. This information helps to select the appropriate material and design.

Equipment Specifications: Obtain detailed specifications of the equipment, including the size, shape, installation method, etc. of the seal.

Define Performance Requirements

Sealing Performance: Clarify the sealing level that the seal needs to achieve, such as waterproof, oil-proof, dust-proof, etc.

Durability Requirements: Determine the performance indicators of the seal such as wear resistance, pressure resistance, temperature resistance, etc.

Special Requirements

Functional Requirements: Whether special functions are required, such as antistatic, shock absorption, corrosion resistance, etc.

Certification requirements: whether it is necessary to comply with specific industry standards or certifications, such as food grade, medical grade, etc.

2. Material selection and design

Material selection

High temperature resistant materials: such as fluororubber (FKM) and silicone rubber (VMQ), suitable for high temperature environments.

Low temperature resistant materials: such as fluororubber (FKM) and polyurethane (PU), suitable for low temperature environments.

Chemical resistant materials: such as polytetrafluoroethylene (PTFE) and fluororubber (FKM), suitable for corrosive media.

Wear resistant materials: such as polyurethane (PU), suitable for high wear environments.

Design stage

Dimension design: Accurate dimension design according to equipment requirements to ensure the adaptability of seals.

Structural design: Design the structure of seals according to working conditions and functional requirements, such as single lip seals, double lip seals, seals with guide rings, etc.

Functional optimization: Consider adding additional functions, such as strengthening sealing, improving wear resistance or antistatic performance.

3. Prototyping and verification

Prototyping

Sample manufacturing: Prototype samples of seals are manufactured according to design drawings. This usually involves the use of mold manufacturing, 3D printing and other processes.

Material testing: Material testing of prototype samples to verify whether they meet performance requirements.

Performance verification

Laboratory testing: Sealing performance tests, temperature resistance tests, pressure resistance tests, etc. are performed on seals in the laboratory.

Field testing: Test seals in the actual working environment to verify their performance under real conditions.

IV. Production preparation and mass production

Production preparation

Mold manufacturing: Make production molds according to the verified design to ensure the accuracy of large-scale production.

Process planning: Develop production process flow, including raw material procurement, production equipment setting and quality control process.

Mass production

Production implementation: Carry out mass production on the production line to ensure that each seal meets the design and quality requirements.

Quality control: Carry out strict quality inspections, including dimensional inspections, performance tests, etc., to ensure the stability and reliability of each batch of seals.

V. Delivery and after-sales service

Product delivery

Packaging and transportation: Pack the produced seals to ensure safety during transportation and prevent damage.

Delivery documents: Provide necessary technical documents, product manuals and certificates of conformity, etc. to ensure that customers can use the seals correctly.

After-sales service

Technical support: Provide technical support and consulting services to help customers solve problems in use.

Quality feedback: Collect customer feedback information, understand the performance of the product in actual use, and provide a basis for future product improvements.

VI. Case analysis

Customization of industrial equipment seals

Background: A certain industrial equipment needs to operate in a high temperature and high pressure environment and handle corrosive media.

Customization plan: Select fluororubber (FKM) as the material, design a double lip seal structure, and conduct high temperature and corrosion resistance tests.

Results: The customized seals successfully meet the requirements of high temperature, high pressure and corrosive media, the equipment operates stably, and the sealing performance is good.

Customization of medical equipment seals

Background: Medical equipment needs to meet food grade and biocompatible requirements.

Customization plan: Select silicone rubber (VMQ) as the material and design it in accordance with food grade certification.

Results: The customized seals passed the relevant certifications, ensuring the hygiene, safety and reliability of the equipment.

VII. Summary

The customization process of seals includes key links such as demand analysis, material selection, design optimization, prototyping, mass production and after-sales service. Through a systematic customization process, we can ensure the excellent performance of seals under various special application conditions and improve the overall efficiency and durability of the equipment. Understanding and mastering this process will help users make wise decisions when facing special sealing needs, thereby achieving the best sealing effect.
