Frequent problems in the production of multi-cavity pen molds? Poor concentricity and difficulty in matching components? Fanstar one-stop solution!

In the production process of plastic pens, the concentricity of the mold and the mating accuracy of each component are the key factors affecting product quality and production efficiency. Many pen-making enterprises often encounter problems such as poor concentricity between the pen core and the pen barrel, and loose matching between the pen cap and the pen barrel during production. These issues not only affect the appearance and user experience of the products but may also lead to quality problems such as ink leakage and poor writing, seriously affecting the market competitiveness of the products.

Do you often encounter these problems in the production of multi-cavity pen molds?

❌ Pen tip, pen barrel, pen cap concentricity deviation LARGE, assembly difficult, high scrap RATE?

❌ Poor compatibility of multi-cavity die parts, inability to guarantee accuracy after core replacement, affecting mass production efficiency?

❌ Traditional mold processing technology is backward, the product has many burrs, and the surface finish is not up to standard?

The root cause of these problems lies in the precision of the mold and the design process!

High-precision concentricity design ensures smooth writing

Concentricity is a key indicator in the design of plastic pen molds, directly affecting the fit accuracy between the pen core and the pen barrel. Fanstar adopts advanced computer-aided design technology and high-precision processing equipment to ensure that the concentricity of molds reaches the industry-leading level. By optimizing the mold structure and conducting multiple simulation tests, Fanstar's multi-cavity pen mold can control the concentricity error between the pen lead and the pen barrel within an extremely small range, effectively reducing the shaking of the pen lead during the writing process, ensuring smooth writing, and enhancing the user experience of the product.

Precise assembly design ensures product quality

In addition to concentricity, the assembly accuracy is also an important factor affecting the quality of plastic pens. Fanstar pays special attention to the assembly accuracy of components such as the pen cap and pen barrel, and the pen core and pen barrel in mold design. By optimizing the gating system and cooling system of the mold, the dimensional accuracy and surface finish of each component are ensured. Meanwhile, Fanstar adopts advanced mold manufacturing techniques to ensure that the tolerance of the mold is controlled within a very small range, thereby achieving a tight fit between the pen cap and the pen barrel and preventing ink leakage and loosening. This precise assembly design not only enhances the appearance quality of the product, but also strengthens its durability and reliability.

Multi-chamber design enhances production efficiency

Fanstar's multi-cavity pen molds can simultaneously produce multiple pen barrels, pen caps and other pen-type components in each injection molding cycle, greatly enhancing production efficiency. Through a reasonable cavity layout and an optimized gating system, Fanstar's multi-cavity pen molds can ensure that the products in each cavity have the same quality and reduce the defect rate caused by process fluctuations. This efficient design not only enhances production efficiency but also reduces the unit production cost, making large-scale production possible.
