3. Durability and Brand Reputation Research different brands and models to find a machine that is known for its durability and performance. Reading customer reviews can also provide insight into the machine's reliability.

In addition to hobbyists, the surge in serger machine sales is reflected in the growing professional realm of fashion design. Small businesses and independent designers often turn to sergers for production efficiency without compromising quality. As more people opt for custom clothing and sustainable fashion practices, the demand for sergers in commercial settings is on the rise. This trend is evident at fabric and craft trade shows, where serger machines are frequently showcased with live demonstrations, attracting significant attention from potential buyers.

It’s allowed me to build up my closet with fabrics ranging from 12 oz. denim and corduroy to lightweight swimwear fabric without breaking a sweat. The machine’s price point is also more accessible than I’ve seen from other companies, especially considering its motor and stitch speed (up to 1,100 stitches per minute). I’ve lost track of the number of times I’ve recommended this machine to other sewers when they’re looking for an economical upgrade for their wardrobe.

In conclusion, the rise in popularity of fully automatic sewing machines has made them accessible to a larger audience, from hobbyists to professionals. With a wide range of prices available, sewers can find a machine that fits both their budget and their skill level. As technology continues to advance, it’s likely that these machines will become even more affordable while offering more features, further revolutionizing the sewing industry. Whether you’re looking to enhance your sewing skills or start a new hobby, investing in a fully automatic sewing machine could be a transformative step in your creative journey.

3. Dust and debris are common reasons for oil seal failure.

Leather is probably the oldest of the lip materials still in common use, but the move towards mass production methods has seen a massive increase in the development of synthetic rubbers which lend themselves to accurate and repeatable injection and compression moulding. Nitrile (NBR) is still by far the most common elastomer for “normal” use, whilst Viton® (FKM/FPM) is rapidly replacing Polyacrylate (ACM) and Silicone (VMQ) for high-temperature applications. Viton® also has high resistance to abrasion and chemical attack making it a preferred elastomer. Recent developments in the use of PTFE for Rotary shaft seals has caused widespread interest particularly for high-speed shaft rotation or poor lubrication applications.

Oil seals are found in a wide range of applications, in virtually every industrial sector. It is essential to select the correct oil seal so that the application in which it is used can run efficiently, free of leaks or other issues. In this blog, we explain which factors you should pay attention to when selecting the best oil seal for your application.

What are Oil Seals and the different types?

What materials are available?

This is one of the frequent reasons for oil seal failure, and this is majorly because of the volatility of any of the elastomer’s constituents. These causative constituents may be part of the elastomer formulation, or gases that got entrapped in the elastomer during the molding process. The deceiving fact about this failure is that sometimes the oil seal won’t show any visual sign of out-gassing, however, sometimes when the out-gassing is extreme, they shrink.
