What type of teeth should your mould reamer have? - 19 October 2020

Using moulds to cast products is a process that is older than many people think. In fact, the oldest cast item is a copper frog that dates all the way back to 3,200 B.C. Since then there has been casting for all kinds of products. Today, most of the glass containers you touch will have been cast. To get them perfect though a mould reamer is necessary. This can prepare and maintain the moulds to prevent flaws. The teeth When you look at a reamer the first thing you will probably notice is the teeth. They are specifically there to smooth the inner surface of the mould. This is necessary to remove deposits of material. It is important to choose reamers with the right type of teeth. They need to be strong enough to remove deposits but not so hard that they will damage the mould itself. To ensure this, you must select the right material. HSS One of the most common options is high speed steel (HSS). This is a popular metal for a huge array of different cutting tools. The alloy...

The critical property that is heat transfer - 07 October 2020

When people require necking profile gauges, they know that they can rely on us. Our company has been supplying these essential utensils for years. We can easily design and manufacture all our models to the highest standards. This is because of our extensive experience. The fashioning of molten glass into the necessary final shape involves the use of several simultaneous processes. For example, you need to withdraw heat from the viscous glass that you are shaping. It is necessary to do this at such a rate that the item keeps it's sought after shape through the formation process. What is heat transfer? One of the critical properties of glass forming would be heat transfer. This is the limiting factor that exists in commercial production speeds. It is the level of heat that moves from the glass to the mould. It decides how long your glass must spend at every stage of the production. Coefficients It is thought that high heat transfer coefficients are indicators of decent...

You must develop your mould designs properly - 28 September 2020

In order to be able to sell the best products to customers, you have to spend years working at it. This is a lesson we know very well after working on improving our blank mould gauges for so long. Our expertise here is unbeatable. Whenever a client approaches us, we go above and beyond to give them what they desire. There is one thing everyone should know about the glass container industry. It is that there are manufacturers who are having issues with retaining knowledge. Many senior employees are beginning their retirements. As for the younger staff, many are not acquiring the right knowledge. This is resulting in major situations that influence production efficiencies. For example, machines may not be working as they should. The areas most at risk in a glass plant are the mould design and production departments. Poor mould development It does not matter how new the forming machine is or how much experience production staff has. Badly influenced production efficiencies are po...

It's important to avoid defects and faults with glass containers - 17 September 2020

At Penico, we have been working with the glass container industry for over 30 years. This has given us the chance to develop a good understanding of the needs of people working in this area. Our team can help by providing a number of quality products. Whether you need a mould reamer, gauge, or another product, you can count on us. Ensuring quality with products You want any glass container such as a bottle to be as high quality as possible. This will protect its contents without causing any issues for the consumer. However, there are various possible defects that you can encounter when creating glass products like these. You need to avoid them so there are no issues. When you have any issues, you need to identify what they are. This could be any number of problems such as a deformation, internal blisters, offset seam, spikes, along with many more possibilities. You can then look at identifying the cause as it is much easier to do this when you know what the issue is first. Thi...

Everything you must know about neck finishes - 09 September 2020

When people desire first rate necking profile gauges, they know they can depend on us. Thanks to our considerable experience, we can create tools capable of helping their users. We design our gauges so they ensure a proper interlocking fit. This works to prolong the life of the mould. With neck finishes in glass containers, the finish dimensions are vital. The reason why is that they have a direct influence on the closure's performance. Dimension consistency is essential to guarantee containment capability. This ensures that the closure or cap fits right and also provides the right opening strength. The finishes on the bottle must meet the right specs. As for the centre of your finish, it should always be aligned with the base's centre. Finding the bottle within a self-centring chuck and rotating the bottle afterwards can make the measurement. The bottle's centre is going to move in a circle of radius equal to the non-vertically or eccentricity. Closure and finish...

How would you go about designing mould equipment? - 26 August 2020

Businesses always want the greatest service. This is also true when they are looking for specific tools to help them with their work. We assist glass container manufacturers by offering them the highest quality blank mould gauges. Thanks to our experience, we can respond to specific demands with very little trouble. The importance of moulds Mould equipment has a vital purpose; it needs to be able to create as many high calibre parts as it can. The equipment tends to be overlooked though. This is when people look at investment and manufacturing costs. The initial price of the gear adds to the total manufacturing costs of every one of the products. So does the ongoing repair and maintenance costs. Moreover, the equipment's condition will have a direct impact on the glass container's final quality. There is something you have to remember here. It is that without first grade mould equipment, there won't be any equally as good glass containers. This fact by itself shoul...

Look out for flow lines and sink marks - 18 August 2020

In order to be successful at something, you need to work at it. At Penico we have been working to offer the best gauges, mould reamer tooling, and many other useful products. As a result, we are now a market leader in our field. Clients can use our products to prepare and maintain moulds. If there are any imperfections, you can expect our utensils to take care of them. Certain moulding defects can be expensive or difficult to address. As for others, you can stop them by altering the whole procedure. You can do this without having to replace equipment or redesign any of your tools. It is usually not hard to avoid defects like these. All you need to do is alter the pressure, temperature, or flow rate of your mould. Flow lines One of the defects you need to look out for is flow lines. These manifest as wavy patterns of a moderately different colour to that of the surrounding area. In addition, they are typically on narrower areas of your component. They could also show up as ring...
