Customized rubber molded parts definition:

Customized rubber molded parts refer to rubber products other than O-ring shapes, which need to be customized according to drawings or samples, customized according to specific needs, and non-standard shaped rubber products. These rubber products typically have special geometric shapes or size specifications to meet the requirements of specific applications. Compared with standard rubber products such as O-rings, sealing gaskets, etc.,OEM rubber parts have more complex and diverse shapes So it is usually referred to as custom rubber molded parts or non-standard rubber parts.

Lixu Rubber can produce OEM rubber parts of various materials and purposes, including Y-shaped rings, V-shaped rings, U-shaped rings, sealing strips, rubber plugs, rubber pads, buttons, gaskets, corrugated pipes and other products of various shapes. The product application scope includes: sealing, waterproofing, oil proofing, gas proofing, connection, fixation, flame retardant, conductive, insulation, food grade, etc

For rubber molded parts, We can design the mold tooling and customization based on the drawings provided by the customer, or project and design drawings based on the samples provided by the customer, providing reasonable design solutions and technical support. We can also choose suitable materials for customers according to their product usage to meet different environmental requirements. The commonly used rubber materials for rubber shaped parts are as follows:

Material selection: 

The material selection of rubber shaped parts depends on their usage environment and performance requirements.

Common materials include but are not limited to:

Natural rubber: has good elasticity and wear resistance.

Synthetic rubber: such as styrene butadiene rubber (SBR), chloroprene rubber (CR), ethylene propylene diene monomer (EPDM), silicone rubber, fluororubber (FKM), etc. Each material has its specific advantages, such as oil resistance, high temperature resistance, low temperature resistance, chemical corrosion resistance, etc.

The specific performance parameters can refer to our rubber material column, and here are some examples for reference.

1. Fluororubber(FKM): It has high temperature resistance and can be used in -30-+250 environments. It is resistant to strong oxidants, oil, and acid and alkali. Usually used for high temperatures

Suitable for oil environments in pressurized environments. Due to its various excellent properties, fluororubber is widely used in industries such as petroleum, chemical, etc

2. Silicone rubber: It has outstanding high and low temperature resistance, maintains good elasticity in the temperature range of -70-+260, and has advantages such as ozone resistance and weather aging resistance. It is suitable as a sealing gasket in thermal machinery. Due to its non-toxic nature, it can be used to produce insulation, insulating products, and medical rubber products.

3. Nitrile rubber: It has excellent resistance to oil and aromatic solvents, but is not resistant to media such as esters and chlorides. Therefore, nitrile rubber is mainly used for oil resistant sealing products.

4. Chloroprene rubber: It has good resistance to oil, solvents, chemical media, and other properties, but is not resistant to aromatic oils. Its characteristic is excellent resistance to weather aging and ozone aging. In production, chloroprene rubber is commonly used to make door and window sealing strips, membranes, and general vacuum sealing products;

5. Ethylene propylene diene monomer (EPDM): It has good resistance to temperature, weather aging, and ozone aging, and is commonly used in door and window sealing strips, as well as in the automotive industry.

Design and Manufacturing:

When designing rubber shaped parts, factors that need to be considered include but are not limited to usage environment, working temperature range, pressure requirements, and contact media. In the manufacturing process, Mold forming methods are usually used, including injection molding, compression molding, transfer molding, etc., to ensure the accuracy and consistency of the product.

In short, Rubber molded parts are customized rubber products according to the special needs of different industries, and their diverse shapes and functions make them an indispensable part of modern industry.

Characteristics of customized rubber molded parts:

Simply put, rubber shaped parts have the characteristics of non standardized size, diversity, and multiple functions, such as:

Non standardization: Rubber molds parts do not have a unified standard specification, but are customized and designed according to specific customer needs.

Generally, Molding production is carried out based on the drawings provided by the customer.

Diversity: Due to different application scenarios, the shape, size, and material of rubber molded parts can vary greatly.

Functionality: The design of rubber shaped parts is often aimed at meeting specific functional requirements, such as sealing, shock absorption, insulation, protection, etc.

The specific performance mainly includes the following aspects:

Sealing performance: Rubber molded rubber parts have good sealing performance and can maintain stable sealing effect in various environments, suitable for extreme conditions such as high pressure, high temperature, and high speed.

Wear resistance and corrosion resistance: OEM Rubber parts have excellent wear resistance and corrosion resistance, and can work stably for a long time in harsh working environments, especially in industries such as chemical, pharmaceutical, textile, casting, etc.

Elastic recovery ability: Rubber materials themselves have good elastic recovery ability, which can quickly restore their original state after being squeezed by external forces, maintaining stable sealing performance

High precision and high efficiency: Rubber molding parts have high precision and high work efficiency, which can adapt to different working environments, be used under long-term continuous operation conditions, reduce mechanical damage, and improve work efficiency.

Customized design: Custom Molded Rubbe parts have high customization design capabilities and can be personalized according to customer needs, suitable for various complex geometric shapes and specific size requirements

Multifunctionality: Custom Molded Rubbe parts have multiple functions such as sealing, wear resistance, corrosion resistance, high temperature resistance, and earthquake resistance.

Application scope:

Custom Molded Rubbe parts are widely used in various industries, including but not limited to:

Automotive industry: used for engine sealing, shock absorption, sound insulation and other parts.

Mechanical manufacturing: used for sealing components, shock absorbers, protective covers, etc. of equipment.

Electronic appliances: used for waterproof sealing, insulation isolation and other parts.

Construction industry: used for sealing strips, waterproof tapes, etc. for doors and windows.

Aerospace: Used for sealing components, shock absorbers, and other high-end equipment such as airplanes and satellites.

Specifically, It can be described as:

In the automotive industry, It is used to manufacture various seals, such as engine gaskets, window sealing strips, etc., which can effectively prevent dust and water vapor from entering, ensuring the performance and service life of the car. In the construction industry, waterproofing membranes, sealants, etc. can be produced to provide good waterproofing and sealing functions for buildings, prevent rainwater leakage, and ensure the safety and durability of buildings. In the electronics industry, Custom Rubber parts are commonly used to manufacture insulation sleeves, shock absorbers, etc. for wires and cables, playing a role in insulation, shock absorption, and protection of wires, ensuring the normal operation of electronic devices. In the medical industry, such as surgical gloves, medical seals, etc., good biocompatibility and sealing performance are required, and custom molded rubber parts can meet these requirements. In the mechanical industry, various rubber shaped seals can be used in machine tools, hydraulic equipment, etc. to prevent liquid or gas leakage, improve equipment efficiency and stability. In the aerospace industry, rubber shaped products such as aircraft seals are also used to adapt to extreme environmental conditions.
