Multi-dimensional composite technology application
Seed
is committed to providing solutions for harsh working conditions to customers
since its establishment, Critical parts and assemblies are designed with carbide,
steel, surface treatment, and a variety of composite technologies integrated to
produce the best fit parts to meet the application needs. These parts are produced to serve oil and gas,
the chemical industry, aerospace, rail transportation, construction machinery,
environmental protection, and other industries. This is one of Seed's key
technologies and can be used to optimize designs for different technologies and
solutions. The products are applied in harsh working conditions, and create countless
success stories.
Shrink fit
Shrink fit is a common used method to assemble steel with
carbide. We can design the interference to match its working conditions
according to the requirements of the customer’s working conditions. Some
products are subjected to high pressures exceeding 103MPa after shrink fit.
Brazing
We can provide different brazing materials. Brazing
methods include high-frequency induction brazing, flame brazing, resistance
brazing, and vacuum brazing which can be applied to products.
Shear strength is ≥200MPa. Steel + cemented carbide, steel + PDC, PDC +
cemented carbide, cemented carbide + cemented carbide, steel + steel and other
technical process combinations can be flexibly applied to customers' different
working conditions and product requirements. We continue to provide our customers
with more comprehensive high-quality precision parts and assemblies.
Glue
The adhesive connection method on cemented
carbide and steel is a simple way to operate at a low cost. Adhesive connections
are adopted for some products which greatly reduces production risks and costs.
Tensile shear strength is ≥24MPa.
Mechanical connection
In some severe working conditions, the design of
the connection mode of critical components is particularly important. We
produce valves and structural parts for petroleum, coal chemical industry, and
other industries. It has a unique connection structure design scheme and can be
designed according to different working conditions. Seed provides connection
methods to help customers increase the service life of their tools and enhance
their competitiveness in the market.
