No catalog, no call center, no "let me check with the team." When you reach out, you reach Mac.
I'm Mac Feng, based in Guangzhou, China. I source aftermarket replacement parts for Hayssen and Bosch VFFS & HFFS bagging lines — the consumables and machined parts that maintenance managers and rebuilders need fast, accurate, and at a sane price.
My approach is simple: drawings, not catalogs. I run a working library of 100+ Hayssen original part drawings, indexed by OEM part number. When you send me a P/N, I don't have to look it up — I open the drawing, check the supplier, and quote.
I work with vetted production lines that I personally visit and qualify — knife makers, polyurethane molders, CNC shops, and stainless cylinder builders. Every order ships with photos. Material certs available on request. One-piece sampling is standard — you validate fit on your machine before committing to a batch.
I'm not a manufacturer. I'm not a marketplace. I'm the technical interface between the drawing on your desk and the part on the production floor. That means I respond in hours, not days. I speak the language of both your engineer and my factory. And when something goes wrong, you don't get passed to a ticket queue.
If your line runs on Hayssen or Bosch and you've ever waited 14 weeks for a $40 part — let's talk.
A P/N, a drawing, a photo, or a sample. Whatever you have. I confirm what it is and what's possible within 24 hours.
Price, lead time, MOQ, and tooling rules — laid out clearly. Single-piece sampling is the default starting point.
Sample arrives. You install it. If it doesn't fit or perform — we adjust. If it does — we move to batch, tooling fees rebated.
Email or WhatsApp — direct line, no gatekeeper.
