Nawa Ne Ainihin Kudin Tsawowar bazara?

You need a replacement spring, but price quotes are all over the place. Zaɓin zaɓi mafi arha zai iya haifar da gazawar gaggawa, but how do you know if you're overpaying for a simple part?

Farashin bazara mai tsawaitawa zai iya zuwa daga 'yan centi don ƙarami, misali daya zuwa sama da dala dari ga babba, custom spring made from a special alloy. The final price is determined by the material, diamita waya, hadaddun ƙugiya, da oda yawa.

A matsayin masana'anta, I see these cost factors every day. It's not just about a piece of coiled wire; it's about the entire process from raw abu[^1] zuwa bangaren da ya gama. Tafiya da maɓuɓɓugar ruwa ke ɗauka daga spool na waya zuwa daidaitaccen tsari, bangaren da aka gwada shi ne ke bayyana kimarsa da farashinsa. Let's break down exactly what you're paying for when you buy an extension spring.

Shin Babban bazara Koyaushe Yana Kashe Ƙari?

Kuna ɗauka cewa babban bazara a dabi'a yana da ƙarin tsada. Amma wani lokacin karami, hadaddun bazara yana da alamar farashi mai ban mamaki. Me ke faruwa?

Ƙunƙarar ƙugiyoyi na al'ada, m sosai haƙuri[^4], and secondary processes like grinding or passivation can cost more than the raw abu[^1] kanta, musamman a kan ƙananan maɓuɓɓugan ruwa.

Waɗannan ƙarin matakan-lokacin aiki da na'ura - sune ke haɓaka farashi, regardless of the spring's physical size.

It's All in the Details

Girman abu ne, but the design's complexity and required precision are more significant cost drivers.

• Diamita waya & Tsawon: Wannan shi ne mafi saukin farashi. Waya mai kauri da dogon maɓuɓɓugan ruwa suna amfani da yawa abu[^1], wanda ke kara farashin.

Yaya Yin oda 10,000 Springs Canza Farashin?

You need just one custom spring, and the quote is shockingly high. You wonder if you're being penalized for a small order. Me yasa farashin ya ragu sosai don babban tsari?
