羅富特模內攻牙機產品核心部件均采用進口原材料，經精密機械加工完成，工藝處理先有高頻淬火使材料性質顯現，在經深冷處理，使核心部件的材料在使用壽命上有顯著提高。
▲深冷處理
工業中，把經過普通熱處理后的材料進一步冷卻到-100℃～-196℃的處理方式叫作深冷處理，它可以降低殘奧含量、促進析出細小碳化物、減少晶間拉應力，進而提高以下宏觀性能：
提高硬度 高速鋼、模具鋼提高HRC硬度1～2度。
提高抗彎強度 440A鑄造不銹鋼的抗彎強度從1135MPa提高到1355MPa。
提高韌性 W6Mo5Cr4V2沖擊功從18J提高到40J。
提高紅硬性 W18Cr4V在625℃的條件下硬度從HRC57.9提高到63.9。
提高尺寸穩定性 95Cr18不銹鋼殘余奧氏體從35%降低至10%。
提高導電性 銅合金Cu_15Ni_8Sn電阻率從2.86×10-7Ω.m降低到1.51×10-7Ω.m。
隨著液氮低溫技術的發展和試驗手段的完善，人們對深冷處理的研究逐步深入，研究范圍現已從鋼鐵延伸到粉末冶金、銅合金、鋁合金及其它非金屬材料。實驗結果表明，深冷處理對于上述材料零件的使用壽命有顯著的作用。
應用行業遍布于航空航天、五金、工具、模具、摩擦偶件、精密加工、量具、紡織、汽車等諸多領域。
Luo Fu Te Luo special mold tapping machine core components are imported raw materials, the precision machining process is completed, the first high frequency quenching of the material properties appear, after cryogenic treatment, the core components of the material on the service life increased 5 ~ 10 times.
▲Cryogenic treatment
industry, further cooling after normal heat treatment of materials to - 100 ℃ ~ 196 ℃ treatment was called cryogenic treatment, it can reduce the content of the paralympic, promoting precipitate fine carbides, reduce the intergranular stress, thus improving the following macro performance:
Improve the hardness of high speed steel, die steel, improve the HRC hardness 1 ~ 2 degrees.
Improve the bending strength of 440 a cast stainless steel bending strength from 1135 mpa to 1355 mpa.
Increase the impact toughness W6Mo5Cr4V2 work from 18 to 40 j j.
Improve red hardness W18Cr4V under the condition of 625 ℃ from HRC57.9 hardness increased to 63.9.

Improve the electrical conductivity of copper alloy Cu_15Ni_8Sn resistivity from 2.86 x 10-7 Ω. Reduced to 1.51 x 10 m - 7 Ω. M.
With the development of the liquid nitrogen refrigeration technology and the improvement of the test method, the cryogenic treatment research gradually thorough, research scope has been extend from steel to powder metallurgy, copper alloy, aluminum alloy and other non-metallic materials. Experimental results show that the cryogenic treatment for the above materials have a remarkable effect on the service life of the parts, can increase 5 ~ 10 times.
Applications throughout the aerospace industry, hardware, tools, moulds, friction coupling parts, precision machining, measuring tool, textile, automobile and other fields.
