BUILT TO YOUR SPECIFICATIONS围绕需求展开
A custom piston starts with understanding the application. Share an engine model, a sample, or a design brief. We work through the geometry and requirements with you.定制活塞，始于理解真实应用。无论是发动机型号、现有样品，还是一份设计需求，我们都可以从这里开始沟通。
You don’t need a complete drawing to begin the conversation.不必备齐所有技术参数，便可开启项目。

A dense forged structure designed for higher combustion pressures, temperatures and engine speeds. Selected products use 4032 or 2618 aluminium, with the alloy chosen for the application.致密的锻造结构，面向更高燃烧压力、温度与转速的应用。部分产品采用4032或2618铝合金，根据工况选择材料。
Selected designs use finite element analysis to optimise stress distribution. Forging supports thinner-wall, weight-conscious designs while retaining the strength required by the application.部分设计通过有限元分析优化应力分布。锻造工艺支持更薄壁厚与减重设计，同时兼顾应用所需强度。
From raw-material forging to CNC finishing, process control and inspection focus on ring-groove quality, dimensional tolerances and consistency.从原材料锻造到CNC精加工，通过过程控制与检验关注环槽质量、尺寸公差及一致性。
Specialist projects can specify high-strength aluminium, steel or titanium-alloy solutions for the relevant piston or component. Material and component scope are defined for the application.针对特殊项目，可就相应活塞或配套部件确定高强度铝合金、钢或钛合金方案，具体材料及部件范围按应用确认。
PRECISION & VALIDATION精度与验证
Piston weight matching is controlled within ±1 g for specified matched sets. Precision tolerances and dimensional consistency are part of the agreed inspection requirements.指定配组套件的活塞重量配组精度控制在±1克以内，精密公差与尺寸一致性纳入双方确认的检验要求。
JND brings OEM experience and OEM-level validation practices into performance piston development, supported by extensive R&D and motorsport resources.精耐德将原厂经验与主机厂级验证实践带入性能活塞开发，结合广泛研发测试及赛车运动资源支持。
