How To Choose A Multi-cavity Pen Mold Processing Manufacturer? Fanstar's 3 Tricks To Solve The Three Major Pain Points in The Industry

In today's rapidly evolving stationery market, a best-selling gel pen often means orders worth hundreds of thousands or even millions. However, many brand owners often fall into traps when looking for multi-cavity pen mold processing manufacturers: inadequate communication leads to a mismatch in mold requirements; The mold design seems qualified but cannot be mass-produced. After much effort, the mold was finally opened, but the injection molded product showed flash, short shot and deformation. Fanstar Injection Molds has been deeply engaged in the industry for 10 years. With the mission of "making every multi-cavity pen mold efficient, stable and replicable", it has solved the above pain points at one time with three hardcore solutions and has become a highly trusted multi-cavity pen mold processing manufacturer in South China.

Inadequate communication means that drawings do not equal requirements

Traditional multi-cavity pen mold processing manufacturers often "put the drawings on the machine as soon as they arrive", resulting in the thin-walled clips that customers want being made into solid columns, and the entire mold being scrapped. Before taking an order, Fanstar initiates a "3D requirement restoration" process: the project manager, mold engineer, and injection molding technician all work in coordination simultaneously. They use 3D visualization models to confirm details such as the pen cap position, pen barrel wall thickness, and multi-cavity balance with the customer frame by frame, reducing the requirement error to within 0.01mm. We adhere to the principle of "communication first, then quotation", ensuring that every multi-cavity pen mold processing plan can 100% reproduce the customer's design intentions, truly achieving zero communication loss.

The mold cannot be mass-produced, and the yield rate is stuck at 85%

Many multi-cavity pen mold processing manufacturers can make the samples look beautiful, but once they are put into mass production on the machine, their true colors are exposed - uneven temperature in the hot runner, poor exhaust in the cavity, and unbalanced ejection, which leads to the machine stopping for mold repair. Fanstar has invested in HAITIAN injection molding machines during the mass production verification stage, simulating 24-hour continuous production and recording the pressure curve, cooling rate and warpage data of each chamber in real time. Through simulation and experimental design, we have controlled the inter-cavity difference of multi-cavity pen mold processing within 0.3g, with a stable yield rate of ≥98%. Customers no longer need to pay for whether the mold looks good or not.

The quality of injection molded products is poor, with frequent appearance defects

Pen barrel flow marks, ink window bubbles, tail stopper shrinkage marks... Any flaw will be infinitely magnified under the large image of e-commerce. Fanstar has formed a multi-person process inspection team, implementing SOP operations for all aspects from the moisture content of raw materials, temperature control of hot runners to mirror polishing after multi-chamber pen mold processing. At the same time, Hexagon's three-coordinate full inspection is introduced, and the tolerance zone is compressed to ± 0.02mm. We also establish a digital ID card for each set of molds, recording the steel batch, heat treatment curve and maintenance log, to ensure that the same quality can be replicated when customers place additional orders two years later.

As a leading multi-chamber pen mold processing manufacturer, Fanstar is equipped with dozens of high-end devices such as advanced CNC machining centers, Dimon mirror EDM machines, and fully automatic three-coordinate inspection lines, with a monthly production capacity of up to 50 sets of multi-chamber pen molds. From 0 to 1, we provide DFM reports; From 1 to 1 million, we promise lifetime maintenance.
