Lubricant Can Reduce Porosity in Die Castings Fochem 国际公司是您的化学专家。
Fochem International, Alrode, South Africa, offers ef- ficient and practical tribological solutions for the global metalcasting industry. Te company has an extensive product portfolio, ranging from lubricants to release agents for the high-pressure diecasting industry. In recent years, Fochem International has improved the lubri-
cating properties of its plunger lubricants through an innovative manufacturing process, providing customers with the highest quality beads for a reliable application. Fochem International’s graphite-based beads are now manufactured with pure, semi- nano graphite that can even withstand extremely high tempera- tures and pressure without starting to oxidize. Fochem International’s latest development, “white beads,” is a valuable asset in addition that offer excellent lubricating properties and a clean casting process. All the plunger beads are round and free flowing, anti-static and dust-free. Tey are suitable for tropical conditions in Asia. Te globules con- sist of a high melting point synthetic wax. As soon as they hit the shot sleeve, the beads start spreading immediately. A thin and even lubricating layer is formed, due to their capil- lary action. All dry plunger lubricants effectively protect the shot sleeve against aluminum erosion; and they can be used in very small amounts to minimize casting porosity. Best results can be achieved in conjunction with Fochem Interna- tional’s dosing machine Dispenser 3D, manufactured by an associate company, Tribo-Chemie, Hammelburg, Germany. In this way, it is ensured that gas and pinholes inside the castings are markedly reduced. Tanks to the pure and capil- lary N-paraffin, the beads are entirely free from aromatic hydrocarbons and hence, eminently environmentally friendly. All these exceptional characteristics ensure optimal lubri-
cation of plunger and shot sleeve, higher quality castings, an overall improved production. Contact marketing@fochem-

Fochem 国际公司是您的化学专家。我们为全球金属 加工工业提供创新、高效和实用的润滑解决方案。凭借持 续改进和创新优势以及与客户密切合作，我们可为高压压 铸工业提供从润滑油到脱模剂不等的广泛产品组合。 近年来，通过对制造工艺实施改进和特殊创新，我们 柱塞润滑剂的润滑性能取得了革命性提高。这种优质润 滑剂可确保客户应用的可靠性。
Fochem 国际公司的石墨玻璃粉使用超纯半纳米石墨 炼造，可经受高温高压而不致氧化。
尤其是我们最新研发的白玻璃粉，不仅具有出色的润 滑性能，还可保证铸造过程的清洁性，是我们现有产品 组合基础上的又一极具市场价值产品。 我们所有柱塞玻璃粉产品都具有完美的流转性和流 动性、防静电、防尘等特点，并可适应亚洲地区的热带 气候。玻璃粉小球体由高熔点合成蜡组成，当其撞击 到压射缸时，玻璃粉立即散布开。这时，由于毛细作 用将形成一层薄而均匀的润滑层。所有干式柱塞润滑剂 都可有效防止压射缸镀铝层腐蚀，但应少量使用，从 而确保铸件孔隙率最低。这些产品与我们的定量配料 机“Dispenser 3D”配合使用可达到最佳效果，，该配 料机由我们位于德国的联营公司 Tribo-Chemie 制造。 通过与配料机搭配使用，可显著降低铸件内的气孔和针 孔。由于采用纯净的毛细管状正链烷烃为原料，玻璃粉 完全不含芳香烃，具有出色环保性能。
这些特性可确保柱塞和压射缸的最佳润滑性、铸件的 高品质以及生产工艺的整体改进，从而赋予 Foche 国 际公司重要的竞争优势。

Research Group Eyes Aluminum-Fiber Combinations 轻量化结构—碳纤维复合材料-铝合金过渡结构
Combinations of fiber composites and aluminum are
increasingly needed in lightweight design in order to match local demands with the respective material properties. A major focus in aircraft and automotive construction is on the development of lean, weight-minimized carbon fiber reinforced polymer (CFRP)-aluminum combinations that are characterized by a high load-bearing strength and minimum susceptibility to corrosion, while at the same time being cost effective. Te Fraunhofer Institute for Manufacturing Technology
and Advanced Materials, a research group at the University of Bremen, Bremen, Germany, has set a goal of developing and
为了满足轻量化设计对各种材料属性的需求，碳纤维 复合材料与铝合金的复合材料的应用越来越多。飞机和 汽车生产中主要关注的是精益、减重的碳纤维复合材料- 铝合金材料的研发，因为这种材料具有较大的承重力、 不易腐蚀，同时，还具有生产成本效益。 不莱梅大学的DFG研究小组“Schwarz-Silber“(FOR 1224)，已确立了研发碳纤维复合材料与铝合金材料复 合的创新性过渡结构的目标。研究小组采用铸造、焊接 和纺织工程技术，规划、设计和开发出了新型的复合概
