年进口模具钢约6万吨。我国每年进口模具约占市场总量的20左右已超过10亿美元其中塑料与橡胶模具占全部进口模具的50以上冲压模具占全部进口模具约40。目前全世界模具的年产值约为650亿美元我国模具工业的产值在国际上排名位居第三位仅次于日本和美国。虽然近几年来我国模具工业的技术水平已取得了很大的进步但总体上与工业发达的国家相比仍有较大的差距。目前我国模具工业的当务之急是加快技术进步调整产品结构增加高档模具的比重通过求品质来求效益提高模具的国产化程度减少对进口模具的依赖。未来我国模具工业和技术的主要发展方向将是———大力普及、广泛应用CAD/CAE/CAM技术逐步走向集成化。现代模具设计制造不仅应强调信息的集成更应该强调技术、人和管理的集成。——提高大型、精密、复杂与长寿命模具的设计与制造技术逐步减少模具的进口量增加模具的出口量。———在塑料注射成型模具中积极应用热流道推广气辅或水辅注射成型以及高压注射成型技术满足产品的成型需要。———提高模具标准化水平和模具标准件的使用率。模具标准件是模具基础其大量应用可缩短模具设计制造周期同时也会显著提高模具的制造精度和使用性能大大地提高模具质量。我国模具商品化、标准化率均低于30而先进国家均高于70每年我们要从国外进口相当数量的模具标准件其费用约占年模具进口额的38。———发展快速制造成型和快速制造模具即快速成型制造技术以便迅速制造出产品的原型与模具降低成本。———积极研究与开发模具的抛光技术、设备与材料满足特殊产品的需要。———推广应用高速铣削、超精度加工和复杂加工技术与工艺满足模具制造的需要。———开发优质模具材料和先进的表面处理技术提高模具的可靠性。——研究和应用模具的高速测量技术、逆向工程与并行工程最大限度地提高模具的开发效率与成功率。———开发新的成型工艺与模具以满足未来的多学科、多功能综合产品开发设计技术。随着计算机软件的发展和进步CAD/CAE/CAM技术也日臻成熟其在现代塑料模具中的应用将越来越广泛。由此该技术也推动了现代塑料模具工业的发展它不仅缩短了塑料模具的设计和制造周期而且也提高了产品开发的成功率并增加塑料模具的价值和市场竞争力。可以预料不久的将来模具制造业将从机械制造业中分离出来而独立成为国民经济中不可缺少的支柱产业与此同时也进一步促进了模具制造技术向集成化、智能化、益人化、高效化方向发展。加入WTO 经济的全球化使企业之间的竞争由过去的局部竞争演变成全球范围的竞争同行业之间跨行业之间的相互渗透、相互竞争日益激烈。为了适应快速变化的市场需求企业必须以最快的速度、最好的质量、最低的成本、最优的服务来满足不同用户的需求而模具制造业的竞争更是如此。CAD/CAE/CAM集成技术就是在这种情况下应运而生的。它已成为现代塑料模具制造技术发展的必然趋势。并以科学合理的方法给塑料模具制造者提供了一种行之有效的辅助工具。使塑料模具制造者在模具制造之前能借助于计算机对制件、模具结构、加工、成本等进行反复修改和优化直至获得最佳结果。总之CAD/CAE/CAM技术能显著地缩短塑料模具设计与制造时间降低塑料模具成本并提高制件的质量是现代塑料模具制造中不可缺少的辅助工具它与“反向工程”及现代先进加工设备等一起成为现代塑料模具制造业中流行且具有竞争力的必要条件。
