Why do you need a reamer for neckring fittings? - 19 April 2021

Neckring fittings are one of the most important parts of the mould for glass containers. Their role is to allow a blank to take the correct shape once it is blown out. However, an issue with a fitting can result in a flaw in the final product. To avoid this, it is important to maintain the fittings and moulds. To do this it is necessary to use a mould reamer. What do reamers do? A reamer is a rotary cutting tool that works to clean up the interior walls of a hole. People may use them to clean up holes from drilling or boring, removing any sharp edges, gouges, or other flaws. However, they are also a common tool for mould maintenance and repair. Again the aim is to remove anything on the surface, leaving it smooth for moulding. The thing to keep in mind is that a mould reamer needs to be a very precise size. It must be able to fit into a mould and make sure the surface is smooth. However, their job is not to remove an excessive amount of material. Typically they will only remov...

What type of glass are you using? - 29 March 2021

Penico Gauges is a name that many businesses in the glass container industry will know. We produce products they can rely on, including blank mould gauges, mould reamers, and more. Without these tools it would be harder to make and maintain their moulds. As a result, we have lots of happy customers who work with us regularly. A choice of glass The many years we have spent in this industry have given us an impressive wealth of knowledge. This includes info about the various types of glass people may try to use. Below are some details about these different products. Soda lime The most popular material for bottles and jars is known as soda lime glass. It is a combination of silica, calcium, and soda. These substances are melted at very high temperatures, creating the molten glass. The amount of silica in the mix can vary to suit the use of the final containers. A higher amount will result in a material with more resistance to thermal shock. That is great for any receptacles th...

Reaming, boring and drilling - What is the difference? - 19 March 2021

One thing you will notice quickly in the manufacturing industry is just how many different processes there are. This offers a lot of options and makes it possible to create such a huge array of products. However, it can cause confusion, especially when one process looks very similar to another. Penico is happy to clear up the matter with reaming, boring, and drilling. We know a lot about the first of these because we are one of the top mould reamer makers in the world. Why is there confusion? The problem is that reaming, drilling and boring all do a very similar thing - they remove material to create a hole. However, there are big differences in how they work and when to use them. Drilling is typically the first step in the process of creating a hole. It requires the use of one or more drill bits to tackle the job. With the right tooling it is possible to drill a hole in various materials, including very durable metals. In a number of cases boring can follow drilling to hel...

Avoiding neckring seams - 08 March 2021

At Penico we understand that the neckring is one of the most important parts of a glass container. We want manufacturers to be able to make jars, bottles and other containers with confidence. To achieve this, we offer a full range of neckring profile gauges. With them the client can measure the neckrings to ensure they are the right size. A seam One issue that some producers can encounter with their glass containers is a seam or fin. This is an unwanted line of glass. They can happen across the top or side of the finish. Their presence can mean it is not possible to screw a top on to the container. As a result it will mean the container is defective and cannot be used. The only option will be to recycle the glass and start again. Check the mould equipment A number of issues can cause the seam on the neckring. However, many of them are due to problems with the mould equipment. For example, it may be that the blank mould recess is too large. The thing to do here is to use a g...

The defects associated with aluminium casting - 25 February 2021

At Penico we commit to creating the most efficient mould utensils. Having spent so long at the forefront of our industry, we understand what it is that customers want. As a result, we are able to produce blank mould gauges that meet and then exceed their expectations. During mould making, people use a process known as casting to pour their liquid material into a mould's cavity. Eventually, the substance cures through cooling or chemical reaction. The final product can then be removed from the mould. Aluminium casting is one form of this process. The thing about it is that it's normal for defects to manifest during the procedure. Some are so compact that they are tolerable and you can easily repair them. Others are more severe however. They result in you having to start from scratch. The following are the irregularities you need to be aware of. Gas porosity We will start with gas porosity. Liquid aluminium can contain huge amounts of dissolved gas. Consequently, it c...

Casting defects and how they manifest - 18 February 2021

Reamers are utensils that people use quite often during their mechanical operations. They are used by hand or as machine driven tooling. Normally, you employ them to create holes inside a mould. They allow users to smooth out and debur any imperfections or edges that may be present. Our business supplies the mould reamer as a tool that allows users to comprehensively repair faults in their moulds. During the process of casting, it is possible to encounter a myriad of product defects. You need to do everything in your power to prevent them. The trick to avoiding these issues is to establish clear tolerances and expectations for quality issues. Prior to doing this though, you must ensure you know about the various forms of casting defects. You must also make sure you know what causes them. Mould material A number of the casting defects link to the mould material you are using. Two common problems here include cuts and washes. These both occur because of surplus metal. The iss...
