树脂传递模塑（RTM）为短批量和中批量提供了一种经济可行的生产方法。本文是一个案例研究的RTM工具的建设，以生产头灯酒吧的巴士。它详细介绍了一种高度填充铝的甲基丙烯酸树脂模具的使用。这种独特的热控模具制造系统具有可忽略不计的收缩和较低的热膨胀系数。这些因素，再加上低成本和短的脱模时间，无论尺寸大小，都能快速、经济地制造出高质量的工具。

RESIN TRANSFER MOLDING (RTM) PROVIDES AN ECONOMICALLY VIABLE PRODUCTION METHOD FOR SHORT AND INTERMEDIATE VOLUMES. THIS PAPER IS A CASE STUDY ON THE BUILDING OF A RTM TOOL TO PRODUCE HEADLIGHT BARS FOR BUSES. IT DETAILS USE OF A METHACRYLATE-BASED TOOLING RESIN HIGHLY FILLED WITH ALUMINUM. THIS UNIQUE SYSTEM FOR CREATING THERMALLY CONTROLLED MOLDS HAS NEGLIGIBLE SHRINKAGE AND A LOW COEFFICIENT OF THERMAL EXPANSION. THESE FACTORS, ALONG WITH LOW COST AND A SHORT DEMOLD TIME, REGARDLESS OF SIZE, ENABLE TOP QUALITY TOOLS TO BE BUILT QUICKLY AND ECONOMICALLY.
