In The Blink of An Eye, A Hundred Pens - Fanstar's Multi-cavity Pen Molds Have Made The Mass Production of Markers And Gel Pens Soar

The pace of the stationery industry is getting faster and faster, but single-cavity molds are like an old ox pulling a cart: one pen at a time, electricity bills are not a penny off, and labor is still paid. Fanstar has directly upgraded "one" to "one" - 4, 8, 16, 32, and even 64-cavity multi-cavity pen molds. In the moment of opening and closing, dozens of marker pens or gel pens are placed simultaneously, tripling production capacity and cutting costs in half. It truly achieves "multiple products from one mold and one-time molding".

Stability is more difficult than speed

To make multi-cavity pen molds both fast and stable, the key lies in the balance of the flow channels.

First, the "running route" of the melt is simulated by the German Moldflow, and then the self-developed hot runner temperature control system is superficially applied. The temperature, pressure and shear rate of each chamber are as consistent as copy-pasting, and short shots, flash and color differences all disappear.

• Is the thin tube of a gel pen afraid of being eccentric? We insert precision guiding inserts and vacuum exhaust, with a concentricity of ≤ 0.02mm, ensuring smooth writing without ink leakage.

Is the fiber tip of a marker pen prone to clogging? Enlarge the gate, densify the waterway, the melt passes through in an instant without burning, the fibers are fluffy, and the ink output is uniform.

A good model, speaking with data

• Core: Imported S136 stainless steel, vacuum quenched HRC50, mirror-polished Ra0.03, resistant to corrosion and wear for over 5 million times.

• Mold frame: Longji standard, HASCO accessories, maintenance like building with Lego.

• Factory physical examination: The 250T high-speed machine runs a 3-hour marathon continuously. Only when the size, weight and appearance are all inspected and found to be in good condition will the "mass-production" label be affixed.

Customer Story

A global stationery giant originally used 8 sets of single-cavity molds, producing 80,000 gel pens per day, with 16 machines and 32 people working non-stop.

After replacing the Fanstar 32-cavity multi-cavity pen mold:

With 4 machines and 8 people, the daily output reached 320,000 pieces. The yield rate soared from 92% to 99%, and all the mold investment was recovered within half a year.

The customer summed it up in one sentence: "The cost has been pushed to the limit, the delivery time is nearly half, and we are receiving orders non-stop."
