On November 26th, Mary, a senior sales manager at Rich Packing, warmly received a delegation from a U.S.-based pharmaceutical company specializing in amoxicillin capsule production. The client’s sole mission: to source a reliable capsule filling machine that could resolve the persistent issues plaguing their current NJP-2500C model – erratic single-capsule dosage, severe powder dust emission, and frequent machine jams – all of which had disrupted their production efficiency and compromised product quality.

Carrying their own amoxicillin powder material, the client traveled to Rich Packing’s Guangzhou factory (2 kilometers from the Canton Fair Complex) after stumbling upon the brand’s technical posts on Facebook, hoping to “take a chance” on finding a viable solution. Thanks to the professional support of Engineer Yang and the outstanding performance of the NJP-3800D high-speed pharmaceutical capsule filling machine, the on-site trial was a resounding success, with the client expressing strong intent to purchase.
The U.S. client revealed that their existing NJP-2500C automatic capsule filler had become a major bottleneck in amoxicillin production:
“We’ve struggled with these issues for over six months, testing various adjustments and even consulting third-party technicians, but nothing worked,” the client shared. “We saw Rich Packing’s posts on Facebook about solving fine powder filling challenges, and since we were already in China, we decided to visit their factory and give it a try.”

Upon the client’s arrival, Engineer Yang immediately initiated a 20-minute material characteristic test on the amoxicillin powder. Using specialized equipment, he analyzed key properties: low fluidity (angle of repose >35°), high hygroscopicity (absorbing 8% moisture in ambient air), and strong electrostatic aggregation tendency – the root causes of the client’s problems. Based on these findings, Engineer Yang fine-tuned the NJP-3800D powder capsule filling machine’s parameters, including adjusting the feeding speed, optimizing the filling pressure, and calibrating the anti-sticking settings.

When the client’s powder was loaded into the NJP-3800D capsule filling machine automatic for the trial run, the results exceeded expectations: the machine operated smoothly without any jams, the single-capsule dosage deviation was controlled within ±0.5% (well below the industry’s ±2% standard), and dust emission was nearly eliminated. The client watched closely, taking notes and capturing video of the stable operation, with visible satisfaction on their faces.
Engineer Yang then walked the client through the technical principles behind the NJP-3800D’s success, breaking down the three core issues with fine amoxicillin powder and the pharma capsules filling machine’s targeted solutions:

Impressed by the NJP-3800D high speed capsule filling machine’s performance and Engineer Yang’s professional explanation, the client praised Rich Packing’s technical expertise: “We’ve visited multiple manufacturers, but Rich Packing is the first to thoroughly analyze our material and provide an on-site solution that works. The NJP-3800D addresses every pain point we have – stable dosage, no dust, and no jams. Barring any unforeseen circumstances, we are committed to purchasing the NJP-3800D auto capsule filling machine and look forward to a long-term partnership.”
