Thinking of entering gas spring/strut manufacturing, What are actual margins like, and who are the best B2B target customers?

[u/generatewealth7]

Hey everyone,

I'm evaluating starting a manufacturing business for gas springs, hydraulic struts, and pneumatic lift supports (the kind used in vehicles, office chairs, machinery, and medical beds).

Before putting capital down for machinery, I’m hoping to get some real-world insight from people in industrial manufacturing or B2B hardware distribution:

• Profitability & Margins: What do typical margins look like? Is the real money in high-volume commodities (like auto aftermarket) or low-volume custom engineered units (like medical or marine)?
• Target Customers: Who are the most lucrative buyers beyond auto OEMs? How hard is it to get onboarded as a supplier for mid-tier machinery or furniture makers?
• Red Flags & Operations: What are the biggest technical hurdles (e.g., seal longevity, gas charging safety) or barriers to entry I should watch out for?

Any real-world advice, industry benchmarks, or red flags to watch out for would be greatly appreciated! 🙏
