Detailed Introduction

Characteristics of Tungsten Alloy Fishing Weights
1. Small size
Even when heavy, it’s still smaller than traditional lead fishing sinkers, making it less detectable to fish. Moreover, it allows for effortless fishing even in deep waters.
2. The material is hard.
It cannot be retrieved if it becomes lodged in the fish’s mouth. Traditional lead fishing sinkers are relatively soft; once swallowed by a prey, they tend to get stuck and are difficult to remove. In contrast, tungsten‑alloy fishing sinkers are much harder and can be smoothly extracted from the fish’s mouth.
3. Strong wind resistance and a pleasant hand feel.
Compared with lead fishing sinkers, tungsten‑alloy sinkers offer superior density and wind resistance, providing a better feel in the hand and increasing the hook‑up rate.

Our company offers fishing sinkers, tungsten balls, and tungsten sinkers in a variety of shapes—such as bullet‑shaped, droplet‑shaped, tubular, and rod‑shaped—with an extensive range of models and a complete selection. If you have any requirements, please feel free to call or write; we can manufacture according to your drawings or assist you with design.

What does MIM technology mean?

MIM technology is a novel component‑manufacturing process that integrates plastic injection molding with powder metallurgy.

During the injection molding process, is the metal material melted?

No—only the binder is melted, allowing the powder to flow like a plastic material. Cooling the binder imparts sufficient strength to the part. The part is then sintered to achieve a very high density, meeting its required mechanical properties.

Why use the MIM process?

When a component is difficult to manufacture using conventional machining or casting processes, or when machining would be prohibitively expensive, or when the part has specific material requirements, the MIM process offers distinct advantages.

Which metal materials can be used for production?

Almost all metal alloys can be used in the MIM process, but the commonly employed materials today are stainless steel, iron, tungsten alloys, and cemented carbides. Brass and bronze are not economically viable for this process. Zinc–aluminum alloys are typically processed by die casting.

Will the delivery lead time be very long?

Mold lead times typically range from 4 to 5 weeks, while sample or delivery turnaround is 1 to 2 weeks; delivery schedules can also be adjusted to meet specific customer requirements.

Can MIM technology be used to manufacture any complex product?

MIM technology also has limitations: product dimensions cannot be excessively large, with a typical maximum weight limit of 300 grams; additionally, very thick or very thin cross-sections are likewise constrained.

What equipment is used in the MIM process?

The equipment used in the MIM process includes mixers, injection molding machines, degreasing furnaces, and sintering furnaces, among others.

Can MIM be heat-treated or electroplated?

Like traditionally machined components, MIM parts can undergo heat treatment, polishing, and electroplating.
