Technetics Group Japan Company Overview

Metal seal for canisters. Good news for substances that cannot use resin or elastomer seal materials! By adopting metal seals, helium leak tightness has been achieved.

We would like to introduce a case where our "HELICOFLEX Delta Seal" was adopted for seals used in canisters by a chemical company. The specifications for the chemical company's canister seals required reliability to achieve helium leak tightness under both vacuum and positive pressure, as well as excellent durability, which ruled out the use of resin or elastomer materials. After adoption, helium leak tightness was achieved, and the design tightening pressure was lower than usual, resulting in reduced bolt load and a decrease in the number of bolts for the canister cover, which has limited space. 【Case Overview】 ■ Challenge - Desire to repeatedly transport chemicals with helium leak tightness ■ Results - Achieved helium leak tightness - Reduced bolt load due to lower design tightening pressure, leading to a decrease in the number of bolts for the canister cover - Also serves as a solution for PFAS measures *For more details, please refer to the PDF document or feel free to contact us.

No need to change the size or number of existing bolts? A must-see for those struggling with "wanting to eliminate gas permeation and gas release from vacuum rubber O-rings" in semiconductor manufacturing equipment!

Our "Delta Beta HNRV" is a combination of a delta seal designed with a low tightening pressure (Y) and a specially processed internal spring, achieving replacement of rubber O-rings, performance enhancement, and PFAS-free status. For those who have concerns such as: "I want to eliminate gas permeation and gas release from rubber O-rings." "I cannot change the number or size of bolts on existing flanges." "I am troubled by PFAS in rubber O-rings." This metal seal is recommended. 【Features】 ■ Mainly for ultra-high vacuum applications ■ Even lower design tightening pressure than before ■ Can be replaced with elastomer O-rings ■ Two delta-shaped protrusions on the contact side of the cross-section ■ PFAS-free This does not guarantee compatibility with existing flanges. Specifications for existing flanges are required. For more details, please download the PDF or feel free to contact us.

Set of NW/KF flanges for ultra-high vacuum, dedicated helico and delta, and dedicated clamps! QDS: Quick Disconnect System

The "Quick Disconnect System (QDS)" combined with the HelicoFlex series significantly reduces assembly time while achieving ultra-high vacuum. It can accommodate everything from NW/KF small diameters to custom products. The RH type, which allows for remote operation, is suitable for reducing operator exposure, in radioactive environments, and when maintenance space is limited (video available). 【Features】 ■ Structural verification completed with FEA (Finite Element Analysis) ■ Non-magnetic (optional) ■ Compatible from NW/KF10 to large diameters *For more details, please refer to the PDF document or feel free to contact us.
