Key Takeaways – Implementing recycled plastics in HVAC requires strict quality control on Melt Flow Index (MFI) to prevent inconsistent molding pressures. – Post-Consumer Recycled (PCR) materials often require “compatibilizers” to maintain impact strength in structural components. – Bio-resins like PA11 (Castor Oil-based) are viable for specific high-heat spacers but remain cost-prohibitive for large housings. […]

Key Takeaways – Insert molding HVAC parts provides superior pull-out strength and torque retention compared to post-process heat staking. – Pre-heating metal inserts is critical to minimize residual stress and prevent “hoop stress” cracking in the plastic boss. – Component assembly reduction is a primary economic driver; integrating fasteners during molding eliminates secondary labor. – […]

Key Takeaways – HVAC rapid prototyping (SLA/SLS) validates geometry and airflow paths but rarely duplicates the chemical resistance or thermal stability of final molded parts. – Mold flow analysis is the critical “digital bridge” that predicts warpage and gate locations before any metal is cut. – Using “Soft Tooling” (Aluminum 7075) can bridge the gap […]

주요 요점 – 내화학성 플라스틱은 냉매뿐만 아니라 함께 순환하는 합성 오일(POE/PVE)도 견뎌야 합니다. – 응축수 팬 재료 선택은 오일 잔여물로 인한 응력 균열을 방지하기 위해 많은 공장에서 ABS에서 폴리프로필렌(PP)으로 전환되었습니다. – PEEK 대 PPS: PEEK가 우수한 연성을 제공하는 반면, PPS는 업계 […]
