what information are required for custom sealing parts

Customised seals require the following key information to ensure the product meets your specific requirements:
 
1. Product Specifications and Design Requirements
This forms the core basis for custom seals and necessitates clarification of the following details:
Dimensional Parameters: Including critical dimensions such as the seal’s inner diameter, outer diameter, and cross-sectional diameter. Precise dimensional tolerance requirements must also be specified here.
Material Specifications: Designate the seal material, such as rubber (EPDM, silicone, etc.), metal, or composite materials, along with required performance metrics including hardness, tensile strength, and temperature resistance.
Operating Environment: Provide a detailed description of the environmental conditions the seal will encounter, including operating pressure, temperature range, contact media (oil, water, chemicals, etc.), and any special requirements such as dustproofing or radiation resistance.
2. Application Scenarios and Functional Requirements
Seal Type: Specify whether for static sealing (e.g., flange connections) or dynamic sealing (e.g., rotating shafts, reciprocating motion).
Performance Targets: Define the sealing grade, such as permissible leakage rate standards (e.g., extremely low leakage rates for nuclear radiation seals).
3. Relevant Technical Standards and Certifications
Should your application involve specific industry standards or certification requirements (e.g., GB/T, ISO, ASTM), please provide these to ensure product compliance.
4. Samples or Drawings (if available)
Providing existing samples or design drawings will significantly aid suppliers in accurately understanding your requirements and ensuring the final product aligns with your expectations.
5. Procurement and Commercial Information
Order Quantity: Specify the required custom production volume.
Delivery Timeframe: Outline your expected delivery schedule.
Additional Requirements: Such as packaging specifications or preferred shipping methods.
Summary: The more detailed and precise the information provided, the better the supplier can tailor seals to meet your requirements. It is advisable to prepare the above details early in the communication process and engage in thorough technical discussions with the supplier
