keensert와 helicoil의 차이점은 무엇입니까??

Keensert와 Helicoil은 모두 나사산을 수리하거나 강화하는 데 사용되는 나사산 인서트입니다, 그러나 그들은 뚜렷한 차이점을 가지고 있습니다:

Basic Information
킨서트: A solid bushing style insert threaded on both the inside and outside with keys on top.
Helicoil: A precision-formed continuous wire coil resembling a spring.

Design
킨서트: Features keys or wedges on top that are hammered into grooves through the threads to lock the insert in place.
Helicoil: Has a diamond-shaped helically formed wire coil that screws into a threaded hole to form a mating internal thread.

설치
킨서트: Easier to install than Helicoil, as it doesn’t require a special installation tool and there’s no tang to remove.
Helicoil: Requires a special tool for installation, and the tang (if present) needs to be removed.

Strength and Durability
킨서트: Stronger than Helicoil, especially in high-temperature and high-torque environments.
Helicoil: Provides permanent, wear-resistant threads but is less strong than Keensert.

Cost
킨서트: More expensive than Helicoil.
Helicoil: Considerably less expensive than Keensert.

Typical Applications
킨서트: Used in heavy-wear, high-vibration, high-heat situations where space saving isn’t a concern and hole depth is limited. Common in aerospace assemblies like transmission housings and suspension units.
Helicoil: Ideal for reducing costs and minimizing space. Suitable for creating permanent strong threads in softer materials like aluminum, titanium, and magnesium alloys in lower heat environments.

Keenserts are better for high-strength applications and environments with high temperatures and torque, while Helicoils are more cost-effective and suitable for softer materials and lower heat environments.
