① Problems

Eye hole and seeding has happened at painting

process to car bumpers. They installed S company’s filter. The filter works moments after they replace filter but defect had happened in a second.

(percent defective 10%)

②Investigation

After measuring the compressed air front

side of electrostatic painting robot

controller through filter from S company,

detected 2000 particles/ℓof 0.3μ

impurities.(element replacement has done 5month earlier)

After measuring air through our

3 in 1 filter, confirmed zero of

0.3u impurities.

④Effect

After measuring the compressed air through

filter from S company detected about 800 particle of 0.3μ impurities, whereas through our T-107A-1000 hadn’t detected particle of 0.3μ.

In fact, defect rate of painting robot which installed our T-107A-1000 was almost 0%, but S filter still had eye hole and seeding.

Establish a difference of performance, customer install T-107A-1000 at other four painting robots.

③Improvement Plan

Installed our T-107A-1000 to a painting robot out of five robots and compare the air quality with S company’s filter(after replace each filter).

Cause of defect was air quality

①Problem

In the powder coating line of the panel of the

air conditioner, Dama and Hageki frequently occured. The reject rate became 10% or more, and it required substantial time for resurfacing.

②Cause

The Screw compressor of 100 horsepower are used.

Because the outflow of oil was suspected, the measurement was executed to find 0.3μ or more about 200,000 of impurities not less than 0.3μ detected.because the outflow of oil was thought,

This seems to be the cause of Dama and Hageki.

③Improvement Plan

T-110A is installed before the powder

coating booth after draining and drying.

④Effect

The resurfacing decreased bay a large degree.

A defective number decreased.

Reject rate about 10% About 1%

T-110A are set up before each powder coating booth (five places).

①Problems ②Investigation

③Countermeasure ④Advantages

Although the customer separated the painting work area from the outside, the compressed air included a plenty of impurities.

[Air quality measured]Compressed air contained about 100 pcs/L of impure particles of 0.3u, which cause the painting failure.

Customer installed 10 units of 3in1 Multi Dry Filter T-105A-1000at Blow and Paint processes.

0.3u particles App. 100 pcs/L

0.3u particles 0 pcs/L

※Eliminate bubble failure using clean air that contains no impurities.

There happened tiny bubble flaws at the painting process of high class unit bath fabrication factory. The failure rate is about 5 to 7% and even a tiny dot makes a product defective.

Customer provides value-added living equipment using painting technology of automobiles, which applies to high class SMC bath and wash place with hydro-painting.

It is normal to control air with zero particles of 0.3u at high rank painting factory.

Customer has exited with the great results of almost no failures.

Our 3in1 Multi Dry Filter contributed to customer’s perfectness.

Frequently stopped inspection machines caused by causeless malfunction of chuck cylinder. Despite their desire for unattended inspection during night there were operators at all times to improve stopping trouble.

Scattering oil mist in the inspection machine.

Only company K’s simple filter in the inspection machine

Detected plenty of impurity particles in the air.

The inspection machine maker’s opinion was that “the impure oil got mixed in the oil less cylinder.”Hypothesized that “the oil from the compressor got mixed in the air” and measured the air.

Installed our filter and demonstrated 0 impurity particles

in the air.

Discovered the factor by measuring the air and installed 3in1 Multi Dry Filter T-105A-1000 x7 in each inspection machine. Installed model

Customer had concerns with product faults due to the followings which would be included in the compressed air that blew products directly.

1) water drop, 2) impure particles, 3) fungi/bacteria

Although customer has adopted the quality management system using AIB, impure particles of more than 0.3u size were found about 200 pcs/L in the compressed air. Since filters used are not antibacterial for both domestic and foreign made, they had not protected completely.

Detectimpure

particles

To remove harmful elements, antibacterial 3in1 Multi Dry Filter with bacterial elimination was installed at the direct air blow processes such lines as loaf of bread, western confectionary, and Japanese confectionary, mainly at packaging lines.

T-103A-AB through T-110A-AB were adopted.

Per customer decision, our antibacterial 3in1 Multi Dry Filter with bacterial elimination was adopted as a standard filter for the packaging lines. Hereafter, the filters have been used at 25 works and associated companies nationwide. (Elements are changed every 6 months to 12 months)

※不純物を取り除いたクリーンエアーを使う事で油付着問題の改善を図る

カテーテル等医療機器メーカーであり、社内定期検査により製品に基準値以上の油分を確認。

①フィルター設置後社内定期検査しましたが、油分は確認されていません。

②クリーンルームの汚染防止に繋がった。③ワンユニットなので、狭い作業台に設置しやすい。④スケルトンの為、エレメント変色が目視確認でき管理しやすい。

There occurs water leakage from pipes and causes water droplets in the factory.

Customer cannot stop production lines nor make pipes into pieces.

It passed 20 years after the factory construction. Sealing tape of pipe joints also deterioratedand therehappened leakage of air and water.

Customer satisfied with the repair without stopping lines or deconstructing pipes.

Water was drippingbefore repair.

Could stop leakage easily.

Simple repair with LLFA taping

This also made possible with repair of several hundred yen instead of vendor cost of several 10K yen each call.

Because of aged pipes, stopping one leakage generated another leakage randomly, makingthe customer helpless.

配管からの水漏れが発生し、工場内に水滴が落ちてしまう。

製造ラインを止められず、配管をばらす事も出来ない・・・

工場建設後20年経過し配管継手部の水だけでなく、シールテープも劣化しておりエアー・水ともに漏洩していた。

製造ラインを止める事なく(配管もばらさず)修理が行え、大変喜んで頂きました。

施工前は水滴が滴っています。

簡単に止める事が出来ました。

LLFAテープで簡単修理

業者を呼ぶと1回、数万円の費用が発生しますが、これからは数百円の費用で即修理が可能になりました。

配管の老朽化により、「こっちを締めるとあっちが漏れる」という状態で大変困られておりました。

③Countermeasure ④Advantages

Although 90% iron powder contained in the cutting oil for the shaving process machine was removed by the magnetic separator, it was unable to remove contaminations generated in the preceding process of shaving, and the impurities scratched the surface of the cutter.

Tank

・Unscratched surface of the cutter.・Increased production efficiency.・The cutting oil of the each shaving process machine was cleaned up with In-line Magnom Clear20 and it made the cutting oil’s life extend longer.

Installed Clear5 x 3 / Clear10 x3at the drive gear borerand the shaving process machine as a inferior measure.

Installed In-line Magnom Clear5 on a trial basis.

Magnet separator

As a result of 750 pcs processing, a large amount of contamination adhered to In-line Magnom.

シェービング加工機切削油に含まれる鉄粉はマグネットセパレータで90%くらいは取り除けるが、シェービング加工機前工程で発生するコンタミは除去できず、カッター面にダメージを受け、歯面キズの発生原因になっていた。

タンク

・歯面のキズ発生がなくなった。・キズがなくなることによって生産効率が上がった。・各S/V機の切削油を抜き切削油をクリア20(2台67万円)にて清掃して切削油のロングライフ化を進める。・ドライブギア内径加工、S/V加工機に不良対策として、

クリア5 3台(37万円)、クリア10 3台(62万円)取り付け。

①Adoption reason ②Illustrative picture

③Experimental proof ④Another approach

Installed In-line Magnom following the existing filter.

Contaminations accumulated as expected. Made a valuation on the filter as a accuracy improvable article.

Room temperature of device usage environment must be24℃±1, promoted heat loss using corrugated plastics tothe air-conditioning and the part of the device, andcontributed to device failure prevention and performanceretention.

Installed In-line Magnom Clear5 to improve processaccuracy and prevent scratches because the existing filterattached to the newly introduced the precision formingsurface grinder was capable of grinding to flatness 5μ.

①採用目的 ②設置状況

③効果の実証 ④その他の改善取り組み

既存の濾過フィルター通過後マグナムを取り付け

予想していた通り、コンタミの集積が出来ており、精度の向上に貢献できる物として評価頂いている。

機器使用環境の室温が、24℃±1に設定必要である為、エアコン空調及び機器の廃熱部にダンプラを使い放熱

の工夫を行い機器の故障防止と性能維持を行っている。

新規導入の超精密成形平面研削盤の平面度0.1μまで可能な研削盤に取り付けてある既存の濾過式フィルター

5μ精度である為、加工精度の向上とスクラッチ傷を防ぐ為、平面研削盤導入と同時にマグナムクリア5“を設置
