COMPANY CAPABILITIES

Material, manufacturing and delivery—connected as one clear supply chain.

Starting from a drawing, sample or operating condition, Maibos supports standard-volume supply and custom rubber development with clearly aligned materials, production stages and inspection requirements.

01
Manufacturing experience

20 years in rubber sealing production

NBR / FKM / VMQ / EPDM
Read capability details

Experience built through daily production and repeat orders informs our work on material direction, dimensional confirmation, tooling evaluation and production handover. Common elastomers are discussed against media, temperature, pressure and motion before a part is defined.

02
Product portfolio

Static seals, dynamic seals and fluid-storage parts

O-RING / OIL SEAL / GASKET / BLADDER
Read capability details

Our scope includes O-rings, oil seals, rubber gaskets and hydraulic crimping-tool bladders. Standard sizes and custom geometries can be reviewed from drawings, samples, grooves or equipment interfaces, with hardness, colour, tolerances and packing agreed before production.

03
Delivery capability

About 50 people, connected across each handover

DRAWING / SAMPLE / PRODUCTION / INSPECTION
Read capability details

Commercial, technical, production and inspection work is coordinated within one team. Projects move through requirement review, drawing or sample confirmation, moulding, trimming, inspection and packing, with key dimensions and agreed checks carried into repeat production.

04
Cross-border coordination

Export experience in Mexico and Italy

MEXICO / ITALY
Read capability details

We support multilingual communication, specification confirmation, packing requirements and logistics documentation for cross-border orders. Protection against moisture, compression and handling is discussed according to product form, route and the customer’s agreed requirements.

01

A focused range for essential sealing tasks.

Begin with the function of the seal, then align material, geometry and production requirements.

Our regular scope includes O-rings, oil seals, rubber gaskets, flat seals, rubber washers and custom-moulded parts. Dimensions, profiles, hardness, colour and packing can be reviewed against the project requirement.

02MATERIAL + DEVELOPMENT

Compare the material direction and development path together.

A polymer name is only a starting point. Media, temperature, pressure, movement, geometry and inspection requirements determine the final compound and part.

01NBRNitrile rubber O-rings

A practical starting point for oil resistance, abrasion resistance and general industrial sealing. Commonly reviewed for hydraulic, pneumatic, machinery and oil-contact applications.

02FKM / FPMFluorocarbon O-rings

Selected when heat, oils, fuels or many chemical media require stronger resistance than general-purpose rubber. Compound choice still depends on the exact fluid, temperature and exposure time.

03MQ / VMQ / PVMQSilicone O-rings

Known for flexibility across a broad temperature range and resistance to weathering and ozone. Special grades and compliance requirements must be confirmed for each application.

04EPDMEPDM O-rings

Well suited to many water, weathering, ozone and selected hot-water or steam conditions. Generally not selected for petroleum oils; the actual medium must be checked first.

Materials
03

Start with the application—not a generic part number.

We turn a drawing, physical sample or application brief into a manufacturable sealing part. The review links operating conditions, material direction, geometry, tooling, sample validation and inspection requirements before repeat production.

  1. 01
    Define the environment

    Media, temperature, pressure, movement and exposure.

  2. 02
    Align the compound

    Resistance, flexibility, hardness and compliance needs.

  3. 03
    Validate the geometry

    Size, groove, compression, tolerance and assembly.

  4. 04
    Confirm the handoff

    Drawings, samples and inspection points stay aligned.

STANDARDS + COMPLIANCE

Define the applicable requirement before production.

Requirements vary by size, compound, market and application. We review the relevant standard or document requirement against each project instead of applying a blanket claim.

ISO 3601

O-ring dimensions and tolerances

ISO 3601 requirements can be referenced when reviewing dimensions, tolerances and surface conditions for the project.

REACH

Material information review

Material declarations and supplied information can be reviewed against the destination market and agreed compound.

RoHS

Restricted-substance confirmation

RoHS-related document requirements can be confirmed for the selected material and order before production.

04WORKING WITH MAIBOS

A rubber sealing factory you can work with.

Maibos supports B2B sealing projects from a production base in Zhejiang. We keep the work practical: understand the application, define the part, confirm the inspection points and keep communication clear through delivery.
