Forging is one of the oldest methods to produce steel components by using compressive forces on billet or bar pieces to achieve a finished part. Forgings are featured with dimensional conformity and fewer internal defects such as porosity or shrinkage, compared to the castings. Basically the forging in closed dies can produce precision valve components with net shape, which means less or no second machining operation would be required. To expand the product range we can serve for customers in valve segment, Teamco has joint ventured forging plants in both Taiwan and China. We follow customer specifications and inspection standards for valve components and other industrial applications.

Specifications follow Customer Drawings

With a professional technical team, Teamco has a strict process of reviewing and evaluating customer's requirements. In pursuing the customer-focus, the whole process requires people across functions to understand customer needs and to align efforts continuously with the goal of customer satisfaction. Upon receiving customer's CAD drawings (2D & 3D), we'll examine the dimensions through software for verifying the design availability. Further discussions or communications would be required help accomplish design into real product. Besides, relative documents such as inspections or packaging will also be reviewed by responsible team. All is customer-oriented.

We Provide Quality Forgings Achieve High Strength

Since the structure of forgings ensures wall thickness and dimensional tolerances are uniform, these forgings have great strength which makes them ideal for high-pressure and high-temperature requirements. Our company is also equipped with heat treatment facilities. This is one of the important factors make us advantageous in accomplishing mechanical features assigned by customers. Good quality forgings also help in reducing the need for NDT (Non-Destructive Tests) in some way. We are able to provide forged valve components such as valve balls, bonnets, retainer seats, etc.

Heat treatment to Achieve Required Properties

Steel heat treatment is the process of metal heating and cooling to change their physical and mechanical properties, without change the shape. It is usually used to improve steel hardness, reduce brittleness and decrease metal stress; can also be used to improve formability, machining and characteristics, etc.

ProcessTreatmentStatus (microstructure) / Purpose
HardeningHeating above the critical transformation temperature, then cooling rapidly.Improving mechanical properties, increasing hardness and producing a tougher, more durable item.  Hardened materials are usually tempered or stress relieved to improve their dimensional stability and toughness.
QuenchingCooling metal at a rapid rate.Immersing metal object in oil or water from high temperature for rapid cooling, a portion of chemical components will transform to a hard, brittle crystalline structure.
TemperingHeating metal at a lower critical temperature, then air cooling.Relieving stresses and alleviating brittleness of the fully hardened steel, bringing to a component with the appropriate combination of hardness, strength and toughness for the intended application.
AnnealingHeating then cooling slowly to room temperature.Refining microstructure, enhancing ductility, lowering hardness; getting better machinability or dimensional stability.
NormalizingHeating then cooling in open air.Removing internal stresses, higher strength and hardness, but lower ductility.
(Surface Hardening)
Heating below melting point, in liquid, solid, or gaseous, decomposes to release carbon Quenching.Carburization is a surface-hardening technique in which carbon is added to the surface of low-carbon steel at high temperature. Carbon from the carborizing environment enters the surface of the steel by diffusion, causing the metal to become embrittled.  This brings to hard exterior and soft interior.
(Surface Hardening)
Heating below transformation temperature in gas, salt bath or plasma to release nitrogen.Diffuses nitrogen into the metal surface to create a case-hardened surface.  As a result, a very high strength product with extremely good wear resistance can be produced, with little or no dimensional change.
