This is the process of assembling the product and confirming the acceptance or rejection of the product.<\/h2>\n

\"\"<\/p>\n

We attach necessary parts to products that require assembly and conduct inspections as needed.
\n Especially for products that have been ordered many times before, we carefully check the finished product to ensure
\n it is the same as the previous one.

Product Inspection Method<\/h2>\n

We use calibrated inspection equipment to conduct inspections on stainless steel containers.<\/p>\n

Visual Inspection<\/h3>\n

We visually check if there are any scratches, dirt, or processing defects on the stainless steel products.
\n We also verify this during various post-manufacturing inspections, cleaning, and packaging.<\/p>\n

Standard Dimension Measurement<\/h3>\n

<\/div>\n
\n

We use measurement tools such as calipers, height gauges, and pi tapes to measure the inner diameter, outer
\n diameter, and height of the product.
\n Caliper… A tool to accurately measure diameters and depths.
\n Height Gauge… A tool to accurately measure heights.
\n Pi Tape… A tool to measure the circumference (outer diameter). (Also known as Pi meter\/Pi tape)\n <\/div>\n

<\/div>\n<\/p>\n

Color Check (Dye Penetrant Inspection)<\/h3>\n

<\/div>\n
\n

We apply inspection fluid to the inspection area (mainly the welding area) to check for fine holes and
\n scratches.
\n We conduct this inspection on containers that cannot undergo pressure and airtightness inspections.

<\/div>\n<\/p>\n

Pressure Test (Hydraulic Test)<\/h3>\n

<\/div>\n
\n

We verify if the pressure vessel can withstand the specified pressure.
\n We conduct water pressure testing for pressure-based inspections and air testing for decompression-based
\n inspections.

<\/div>\n<\/p>\n

Airtightness Test<\/h3>\n

<\/div>\n
\n

This test is performed to confirm whether sufficient airtightness is maintained when a specific pressure is
\n applied to the pressure vessel.
\n We carry out the inspection using air (atmospheric air).
\n > Commitment to Quality [Pressure Vessel Inspection]<\/a>\n <\/div>\n

<\/div>\n<\/p>\n

Leak Test (Helium Leak Test)<\/h3>\n

<\/div>\n
\n

We use a leak detector to inspect leaks in seal and welding parts.
\n This can detect minute leaks.

<\/div>\n<\/p>\n

Inspection Documents<\/h2>\n

We create an inspection report after the completion of each inspection.
\n The inspection contents include appearance and dimension inspection, but we also create inspection items and
\n documents as per the user’s specifications.
\n > Thorough support for inspection documents and certificates<\/a><\/p>\n
