Die Cast Aluminum Antenna Housing: Materials, EMI Shielding and Sealing

Die Cast Aluminum Antenna Housing: Materials, EMI Shielding and Sealing

A communication antenna housing has to do three jobs at once: shield sensitive electronics from electromagnetic interference, keep out water and dust in an outdoor environment, and dissipate the heat generated by active radio components — all within a single die cast aluminum part. This article explains why aluminum die casting is the standard choice for antenna and base station housings, how EMI shielding and IP-rated sealing are achieved, and what wall thickness and material considerations affect the finished part.

CNC Aluminium Extrusion Guide For Custom Industrial Parts

CNC Aluminium Extrusion Guide For Custom Industrial Parts

Let’s face it. An aluminium extrusion rarely comes off the production line ready for assembly.The profile may already have the right overall shape, but most industrial parts still need precisely located holes, threads, slots, mounting faces, connector openings or machined...

Wire EDM Machining: Precision Cutting for Hardened Metal Parts

Wire EDM Machining: Precision Cutting for Hardened Metal Parts

Wire EDM cuts through hardened metal with a continuously fed wire electrode instead of a rotating cutting tool, making it possible to machine features and materials that CNC milling can't reach — narrow slots, sharp internal corners, and hardened tool steel after heat treatment. This article explains how wire EDM works, what tolerances and finishes it can achieve, and when it's the right process for a part CNC machining alone can't complete.

Brazed vs Friction Stir Welded Cold Plate: Which Sealing Method to Choose

Brazed vs Friction Stir Welded Cold Plate: Which Sealing Method to Choose

Brazing and friction stir welding (FSW) are the two dominant methods for sealing the channel-and-cover structure of a liquid cold plate, and the choice affects burst pressure, long-term leak reliability, and design flexibility in different ways. This article compares how each method performs under pressure and thermal cycling, what channel geometries each supports, and which applications favor one method over the other.

CNC Machined Optical Sensor Housing: Design, Materials and Manufacturing

CNC Machined Optical Sensor Housing: Design, Materials and Manufacturing

An optical sensor housing does more than hold a sensor in place — it must align the sensor's active area to the optical path, manage heat generated behind the sensor, shield sensitive circuitry from EMI, and often seal against dust and moisture, all within a compact envelope. This article explains what distinguishes sensor housings from general optical housings, the tolerance, thermal, and EMI requirements involved, and the material and machining choices that determine whether a housing performs reliably in the field.

Spring-Loaded Lens Holder Design: Preload, Centering and Machining Considerations

Spring-Loaded Lens Holder Design: Preload, Centering and Machining Considerations

Rigid lens holders can lose contact with the optic — or overstress it — once thermal expansion and manufacturing tolerances stack up across an assembly. Spring-loaded lens holders solve this by applying a controlled preload force that keeps the lens seated and centered across temperature changes and vibration. This article explains common preload mechanisms, how preload force affects centering and wavefront error, and the machining considerations that go into producing spring-loaded lens holders.

마찰 교반 용접: CNC 가공 알루미늄 인클로저 및 하우징

마찰 교반 용접(FSW)은 알루미늄 부품을 고체 상태에서 접합하여 융접에서 흔히 발생하는 용융, 다공성, 변형을 방지합니다. XY-Global에서는 CNC 가공과 함께 FSW를 사내에서 수행하여 밀폐된 알루미미늄 인클로저와 하우징을 단일 제어 작업 흐름 내에서 용접하고 최종 가공할 수 있습니다. 이 글에서는 FSW의 작동 방식, FSW에 적합한 알루미늄 등급 및 조인트 유형, 그리고 CNC 가공과 FSW를 결합하여 밀폐된 고강도 부품의 치수 안정성을 개선하는 방법을 설명합니다.

Precision Titanium CNC Machining: Materials, Tolerances and Machining Strategies

정밀 티타늄 CNC 가공: 재료, 공차 및 가공 전략

티타늄은 높은 강도 대비 중량비, 낮은 열팽창 계수, 뛰어난 부식 저항성, 생체 적합성 등 여러 특성이 결합되어 있어 의료 기기, 항공 우주 시스템, 광학 기기, 정밀 산업 장비와 같은 까다로운 응용 분야에서 선호되는 재료입니다. 그러나 이러한 특성으로 인해 티타늄은 알루미늄이나 강철보다 가공하기가 훨씬 더 어렵습니다. 티타늄에 대한 엄격한 공차와 우수한 표면 마감을 달성하려면 표준 CNC 가공 방식과는 상당히 다른 특정 툴링, 절삭 전략, 절삭유 관리 및 공정 지식이 필요합니다. 이 글에서는 정밀 티타늄 CNC 가공이 무엇을 수반하는지, 티타늄이 왜 독특한 공정 문제를 야기하는지, 가장 일반적으로 사용되는 합금은 무엇인지, 그리고 티타늄 부품에 대한 가공 공급업체를 선택할 때 무엇을 찾아야 하는지 설명합니다.
