ABOUT JNDABOUT JND
精耐德 JND brings product, engineering and manufacturing together for custom piston projects.精耐德 JND 围绕定制活塞项目，连接产品、工程与制造。
OUR APPROACH我们的思路
What engine is it for? How will it be used? What needs to change? These questions shape a meaningful discussion about a custom piston.适用于什么发动机？将如何使用？希望改变什么？这些问题，是一次有价值的定制沟通的起点。
We focus on the details of the part and the requirements of the project. Product suitability, specifications and delivery arrangements are reviewed individually.我们关注产品细节和项目需求，逐项沟通适用性、规格和交付安排。
Our custom approach了解定制方式THE JND APPROACH精耐德的开发方式
An OEM cast sample can provide a starting reference for a forged-piston design. Sample analysis and 3D development are different stages from the finished product.客户提供的原厂铸造样件，可作为锻造活塞设计的起点。样件分析、三维开发与成品是不同阶段。

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。
APPLICATIONS & CUSTOM DEVELOPMENT应用覆盖与定制开发
Replacement and upgrade solutions cover selected Japanese, European and American performance engine platforms, with application-specific matching for competitive and high-performance street builds.原厂替换及升级方案覆盖特定日系、欧系与美系性能发动机平台，为竞技与高性能街道改装提供针对性的匹配方案。
Specialist aluminium and steel piston designs address the high-temperature, high-pressure loads of diesel-racing applications. The design and material are selected for each project.针对柴油赛车的高温高压负荷，提供专项铝制及钢制活塞设计，按具体项目选择结构与材料。
Custom piston development supports specific dimensions, compression ratios and engine combinations, with a flexible approach to project requirements and cost planning.可根据样品、图纸或构想开发定制活塞，回应特定尺寸、压缩比及发动机组合需求，灵活安排开发方案与成本。
