The Application of Lapel Pins in Daily Life
Collar pins are widely used in our daily life and can be seen everywhere. They are commonly used for identity identification, achievement motivation, ability certification, cultural circle promotion, charity and public welfare identification, brand marketing and promotion, etc. There are also many enamel pin enthusiasts who like to collect pins featuring elements such as Disney collar pins, Olympic Games, celebrity support, anime and
cartoon characters, etc.
What is the best material for make lapel pins ?
The common types of metal lapel pins include: stainless steel, stainless iron, brass, zinc alloy. The precious metals are silver and gold. Due to their excessively high prices, people tend to choose ordinary metals for making lapel pins. The material is also a fundamental factor influencing the price. Today, we will talk about the advantages and disadvantages of different materials.
1. Zinc Alloy
Advantages: Excellent casting performance, suitable for complex three-dimensional shapes (such as double-sided commemorative coins); low melting point, easy for die-casting molding.
Disadvantages: Poor corrosion resistance, shorter service life than copper materials; surface prone to oxidation.
Applicable scenarios: Three-dimensional badges, commemorative coins.
2,Copper (Brass / Purple Copper / Bronze)
Advantages: Good ductility, suitable for fine engraving; Purple copper is often used in enamel craftsmanship, with a rich and vibrant surface color and high temperature resistance; Brass and bronze are mostly used in imitation enamel or varnish techniques, with superior texture and suitable for collector-level badges.
Disadvantages: High cost; Purple copper is prone to oxidation and requires surface electroplating protection.
Applicable scenarios: High-end pin badges, commemorative medals (such as Olympic medals, brand logos.
2. Stainless Steel
Advantages: Strong rust resistance, durable; surface can be printed or dripped with glue, bright colors, high cost-effectiveness.
Disadvantages: High hardness, difficult to engrave; color expression is not as rich as copper material.
Applicable scenarios: Outdoor badges, enterprise logos for long-term use.
3. Iron
Advantages: Low cost, easy to process; after electroplating or varnishing treatment, it can have an appearance comparable to that of copper.
Disadvantages: Prone to rust (especially in humid or maritime environments), poor durability.
Applicable scenarios: Temporary event collar pins, low-cost decorative badges.
According to the current manufacturing process, if the budget is very limited and large quantities need to be produced, we suggest using iron. If you need high-end lapel pins for government departments or for long-term preservation, we recommend using vacuum electroplating with a combination of brass, real gold and real silver.
Zinc alloy is a suitable material for medium-priced products. Currently, both Dinies and Sanrio prefer to use this material to make enamel pins.
