冠连五金矿产（香港）有限公司投资成立的中山市正亮精密机械有限公司，从事金属、非金属表面处理技术的开发及机械设备的研制、销售及技术咨询服务。 冠连五金公司从上世纪八十年代即从事于表面处理技术的研发，具备强大力量和技术成果的积累，尤其在低温表面处理技术方面更具独特优势。现投放市场的YJ系列液氮深冷表面处理机，更适合中国及东南亚等发展中的国情，能耗低，操作方便实用，综合性价比高。 该机是一种利用液态氮的急速深冷，使得被处理物件毛边迅速冷冻，在临界脆化状态下，通过高速离心装置，将耐低温复合材料微粒连续、高速喷射至被处理物件，经过反复循环喷射操作，即可在不损伤物件表面的情况下，率、量地去除物件的毛边、飞边、毛刺。 此设备广泛应用于汽车、五金、航天、电子、通讯、IT、3C等行业，适用于处理：橡胶、塑胶、热塑性树脂等高分子材料；锌、铝、镁等合金零部件；电子制品及其它适宜加工的五金制品。是上述产品后道毛边、飞边、批锋去除工艺的设备。 该机自动化程度高，控温，操作简单。加工除毛边效率极高，可大量取代以往的手工操作。在数倍放大镜下观察，产品外表面美观，外观一致性明显优于手工修边。 Crown Lian Minmetals (H.K) Ltd. sets up his joint venture in Zhongshan Zhenliang Procision Machinery Co, Ltd. The joint venture focus on surface treatment process development,equipment design and manufacturing, sales and consulting. We have solid strength on low temp surface treatment with the support from Crown Lian. Crown Lian has accumulated a lot of know-how on surface treatment process. Now we provide YJ series liquid freeze surface treating machines. They are with perfect economics. They can meet most requirements in Southeast Asia and Chinese markets. This trimmer refrigerates parts quickly with liquid nitrogen to embrittlement. Spraying high speed composite grains to the parts processed with centrifugal pump, the edge can be trimmed efficiently but no damage to the surface of the parts This trimmer can be widely used in different industries, such as auto, metal, aerospace, electronics, telecommunication,IT.It can process non-metallic parts, such as rubber, plastics,epoxy, can also deal alloy parts. This equipment is right finishing tool to remove burrs. The machine well controls temperature with high automation technology. It is equipped with imported PLC and man-machine friendly touch screen. People can run it very easily. This high efficient machine can replace the traditionally manual process. Even under magnifier, you can see its nice surface on your parts. It is obviously better than manual work. 产品特点 Feature 1、 适用于加工任意几何形状的：橡胶、塑胶、热塑性树脂等
