Leave the helium leak testing to us. We have received positive feedback for both our entrusted testing services and on-site testing with our equipment.
Our company offers a service where we take custody of your parts and conduct leak testing (leak tests, leak checks, and leak examinations) using a helium leak detector. The leak testing using a helium leak detector has the following advantages: - Helium has a smaller molecular diameter than hydrogen, making it suitable as a test gas for leak testing. - It can detect very small leaks with high precision compared to other leak testing methods (it can find leaks that cannot be detected by submerged methods or air leak testers). - It is equipped with a calibrated leak, allowing for quantification of the detected leak amount. - It can identify leak points. - It is a non-destructive test. - Helium is an inert gas that is safe and does not cause chemical reactions with products. Our staff, who have been involved in helium leak detector testing for many years, will provide thorough explanations and careful inspections to our customers. If requested, we will comment on the possible causes based on the manner of the leak and the behavior of the values when a defective product (NG product) is detected. We offer two methods of service: in-house testing and on-site testing. We respond daily to inquiries from customers in various departments such as research and development, quality assurance, and production technology.

basic information
【Inspection Equipment】 Helium Leak Detector ASM310 manufactured by Pfeiffer Vacuum, Germany *Regular calibration leaks are updated to maintain the reliability of the measurements. 【Testing Method and Detection Sensitivity】 - Detection sensitivity of the vacuum method (spray method) is 10E-3 to 10E-12 Pa·m³/s. *The lower limit of measurement (background) varies depending on the condition of the inspection target, volume, outgassing, etc. - Detection sensitivity of the pressurization method (sniffer method) is 10E-3 to 10E-7 Pa·m³/s. *Using the auto-zero function allows for inspections at effectively -9 power Pa·m³/s. *The pressure for pressurization should be discussed and kept below the pressure of high-pressure gas cylinders. - Other methods, such as the bombing method, etc. The lower limit of detection for other leak testing methods is generally considered to be -3 power Pa·m³/s for the "submersion method" and -5 power Pa·m³/s for the "differential pressure air leak tester." 【Inspection Jigs】 We will devise and prepare inspection jigs tailored to the shape of your products. Please provide any materials or information regarding the shape of the inspection target in advance. 【Inspection Report】 The results of the inspection will be submitted in writing. It is also possible to fill out the format provided by the customer.
Price information
The basic price is calculated based on the following items: - Basic inspection fee - Technical fee - Report preparation fee (depending on the report content) - Individual inspection costs (quoted as needed) - Preparation cost for leak testing jigs (if necessary) - Consumable costs - Repackaging shipping costs - Management fee Prices vary depending on the inspection content.

Applications/Examples of results
【Examples of Inspection Targets】 - Leak confirmation for gas introduction components of semiconductor manufacturing equipment - Welded parts of stainless steel components - Piping components - Automotive parts - Electronic components - Welded parts - Heat exchangers - Sintered materials - Resin components - Helium permeability confirmation for resin materials - Others In consultation with our customers, we conduct leak inspections using methods suitable for the shape and material of the items to be inspected. Inspection results include: - Pass/fail judgment against standards only - Pass/fail judgment and numerical value of leak amount (usually this is what we provide) - Pass/fail judgment, numerical value of leak amount, and graphs of behavior during leak inspection (conditional) We communicate the results based on your preferences. Additionally, while optional, we also accept requests for more detailed information about leak inspection results or any questions you may have. Please feel free to consult with us.
Company information
We are developing a vacuum equipment business centered on "helium leak testing" and "vacuum pump repair," as well as an electronic components business primarily focused on "design and manufacturing of electronic components (transformers)." Additionally, we handle the design and manufacturing of experimental vacuum containers and piping components. As a proposal-oriented company, we strive to present ideas derived from flexible thinking, not just the commonly used problem-solving methods, to our customers, aiming for better results. Our proposal capabilities have received high evaluations and support from everyone. 【Vacuum Equipment Business】 - Helium leak testing (including leak tests and jig manufacturing) - Vacuum pump repair - Sales of vacuum equipment (including used items) - Design and manufacturing of experimental equipment 【Electronic Components Business】 - Design and manufacturing of electronic components "transformers (switching power supply transformers, boost transformers)" - Boost DC converter (DC12V → DC1kV~3kV) 【Exhibition Participation Achievements】 2020: "VACUUM2020 Vacuum Exhibition," "Itabashi Industrial Fair" 2021: "Itabashi Industrial Fair" 2021-2025: "Technical Show Yokohama 2021, 2022, 2023, 2024, 2025"
