言信潔凈室系統(tǒng)工程理念：規(guī)范、適用、超前、經(jīng)濟、耐久。

Guideline of Yanxin Cleanroom System Project:
To insure our Cleanroom System standard, suitable, modern, economical and durable.

言信潔凈室系統(tǒng)工程一直沿用國際最新的標準規(guī)范進行，確保建設(shè)的每一個潔凈室達到國際驗收標準。
Yanxin Cleanroom System has been following the newest international standards and assuring each solution of cleanroom to meet international acceptance criterions.

言信潔凈室系統(tǒng)工程以客戶為本，從不以規(guī)范標準驗收合格為工程合格唯一標準，言信一直認為，客戶滿意的潔凈室才是真正合格的潔凈室。
Yanxin Cleanroom System is customer-oriented, never regard meeting the acceptance condition as the only standard, but make the cleanroom meet customer’s requirements.

在言信，我們要求每一個設(shè)計師、工程師對自己設(shè)計及施工過的工程進行回訪，不管十年前，還是二十年前，不管當時驗收時是得到多么的肯定，都不另外。這不僅僅是我們良好售后服務(wù)的體現(xiàn)，更重要的是通過這些回訪，讓每一個言信人了解自己設(shè)計及施工的工程，在使用的過程中有什么優(yōu)點和不足，為現(xiàn)在的設(shè)計及施工提供寶貴的經(jīng)驗。因此，言信設(shè)計施工的工程都以適用性、耐久性而聞名行業(yè)。
Yanxin requires each designer and engineer to return visit the project designed or constructed by themselves without expense, no matter when the projects were accepted, ten years ago or twenty years ago. It not only reflects our good after-sales service, but also enables each employee of Yeshine to understand the process of design and construction, to differentiate the good and bad points in using and to offer more valuable experience for the current design and construction. Therefore, the Yanxin design and construction is well-known for its applicability and durability.

言信要求每一個設(shè)計師、工程師堅持不斷學(xué)習(xí)新的知識。我們訂閱了國內(nèi)外行業(yè)科技雜志，經(jīng)常請國內(nèi)外專家及潔凈室使用客戶給大家講課，并通過潔凈室工程師同盟經(jīng)常組織技術(shù)交流活動，為的就是不斷充實豐富最前沿的行業(yè)知識，使用言信潔凈室系統(tǒng)工程的設(shè)計及施工具有前瞻性，確保設(shè)計施工的潔凈室數(shù)年甚至數(shù)十年不落后。
Yanxin requires each designer and engineer to keep on acquiring new technique and industry knowledge, so we subscribe many domestic and overseas science and technology magazines, and often invite domestic and foreign experts and users of cleanroom to give lectures and organize technological consultation activities via coalition of cleanroom engineers. In order to keep step with the development of technique, design and construction of cleanroom, we insist the above action from year to year.

言信企業(yè)擁有一流的現(xiàn)代化加工、一流的加工設(shè)備及一流的加工工人，我們的加工廠能生產(chǎn)出潔凈室建設(shè)所涉及的大部分材料及配套設(shè)備，因些言信的潔凈室系統(tǒng)工程具有非常好的性價比。用最合理的資金，建設(shè)最好質(zhì)量的潔凈室，一直是言信追求的目標。
Yanxin owns first-class modernized processing technologies, first-class processing facilities and first-class workman, and our processing factories are capable of producing most materials and corollary equipment involved in cleanroom project, which lead Yanxin Cleanroom System has a good cost performance. The ultimate goal of Yeshine is to construct cleanroom with the best quality and the most reasonable cost.
