Processing technology

TAKAHATA manufactures products by making full use of various processing technologies, including lapping technology for finishing molded products with higher levels of accuracy, seal technology for assuring an extremely high level of waterproofing, and various types of bonding technology for realizing complex shapes. By providing a sophisticated blend of all technologies, we are able to deliver optimal solutions to our customers.

Lapping technology

Fuel pump impeller

Maintaining clearances

The rotation of this impeller, which is designed to be built in a fuel pump chamber, generates pressure differences in order to pump fuel oil. The clearance between the impeller and casing is an important feature of the product.

Material
PPS
Dimensions
40 mm dia., 4 mm thick
Accuracy
Thickness accuracy of 5 µm or less

Flow control part

Achieving a sophisticated blend of flatness and parallelism

Achieving high seal performance requires flatness, parallelism, and surface roughness. Flow path dimension control as implemented for the part facilitates flow control functionality.

Customer-developed grade

Potting

Printed circuit board (water meter)

Technology for completely preventing ingress of water, a natural enemy of electronic parts

Potting technology provides one means for preventing ingress of water. Electronic meters must be completely waterproof since they are often installed in severe environments, including in permanently submerged settings. We have long worked to solve this problem in cooperation with a material manufacturer, leading to the development of potting technology that allows meters to withstand complete submersion for up to eight years.

Welding

Vibration welding

Free welding of large parts

This method of fusion bonding using friction heat generated by vibrating resin parts can be used when welding large parts.

Equipment manufacturer
Branson

Hot-plate welding

Automatic operation at our own facility enables smooth welding.

This method, which involves heating the surfaces to be bonded with heating plates and bonding the molten surfaces before solidification, provides high welding strength. Our own facility automatically performs operations ranging from product clamping to welding completion.

Ultrasonic welding

Accommodating shapes that are highly difficult to bond

This method for fusion bonding by applying ultrasonic vibration to resin parts can be used to weld small products. It features quick turnaround times. TAKAHATA engineers deals with shapes that are highly difficult to bond by studying the design of the welding area in detail.

High-frequency induction heating

Welding technology that delivers a high level of waterproof performance

This technique for heating and welding resin parts by electrifying a metal wire arranged on the surface to be bonded is ideal for use when waterproof performance is an important property.
