Your Supplier Choice Many Be As Important As Your Material Choice

Your organization spends hours working with suppliers to find the optimal balance of price and material grade. You negotiated, compromised, sent RFQ’s and placed PO’s. In the past, many companies didn’t communicate with their suppliers until the next order or delivery was needed.

Not anymore. Surveys tell us that the attitude toward supplier relationships has changed over the past decade. Companies are now realizing the importance of leveraging strategic relationships with their suppliers. In a poll taken in 2016, 63% of procurement professionals had improving collaboration with suppliers as one of their top KPIs for the year.

In today’s competitive market place, I would argue that on some occasions your supplier choice is as important, if not more important than your material choice.

Understanding electrode parameters can improve EDM Efficiency

Robert Fothergill, EDM Applications Specialist with Poco Graphite, recently published an article in Mold Making Technology discussing that understanding all the electrode parameters can improve EDM efficiency. I can’t agree more.

As discussed, sinker EDM machining technology has improved significantly over the years. These changes effect the processes and decisions an EDM machinist will face when running the machine. But, some performance factors remain the same even with the advanced technology:

• Machinability - a balance between easy to machine and resilient enough to withstand the machining process

• Metal Removal Rate – achieving the proper electrode material/work metal/application combination rate so the MRR can be maximized

• Wear Resistance – maximizing the electrode to produce and maintain detail related to its wear and...Read more

Consider particle size rather than density when choosing an EDM Graphite Material

Anyone who has ever purchased graphite materials knows that the physical properties of the material are important. You want to use the right product for the application. But in efforts to promote less expensive products, and compete on price, many distributors are focusing on the density of the material. They are presenting density as an indicator of enhanced quality. I would argue that particle size is by far more important than density when choosing the quality of a product.

All EDM Graphites are evaluated using the following physical properties:

• Particle Size
• Apparent Density
• Flexural and Compressive Strength
• Hardness
• Electrical Resistivity

EDM Graphite is made from petroleum coke, a manufactured carbon product. The petroleum coke is pulverized into small particles and mixed with a...Read more

5 Reasons to Consider Copper Impregnated Graphite for Electrodes

Copper impregnated graphite is a material with the qualities of both graphite and copper. It is a graphite material manufactured with a controlled amount of interconnected porosity which is then infiltrated with copper by capillary action in a furnace. The impregnation process is performed at 2400 degrees F (1300 degrees C) in a controlled atmosphere to eliminate oxidation. The graphite must be heated first and then completely submerged in molten metal. Once completely surrounded by molten copper, several hundred atmospheres of pressure are applied to force the metal into the pores of the graphite. After the pores are fully infiltrated, the excess metal is removed and the graphite is allowed to cool.

Shops generally use copper to make electrodes when they have a need to provide a better surface finish and better flushing. They generally use graphite when they...Read more

5 Reasons to consider CFC Materials for Use in Vacuum Heat Treat Furnace Applications

Many of our customers are inquiring about the benefit of using CFC Materials in their Vacuum Furnace and other Heat Treat applications. While there are many benefits, from increased furnace capacity to quicker turnaround time, there are 5 main benefits that deserve attention:

1. CFC Materials provide High Strength while Light Weight Thanks to their special fiber structure, CFC is very low weight and robust, especially when it comes to the behavior of fracture and mechanical resistance. Racks and workpieces made of CFC are 8 to 10 times lighter than classical racks. Consequently, they facilitate processes and working cycles and even contribute to the prevention of accidents. With high strength and low weight, CFC jig assemblies are used for vacuum heat treatment and brazing of turbine blades, oil coolers, stainless steel brazing and sintering.

The Skills Gap May Be the Biggest Opportunity of a Generation

The manufacturing industry of a country is directly proportional to its gross domestic product (GDP). In the US, every dollar spent on manufacturing contributes $1.32 to the economy, and manufacturing supports more than 17 million workers.

Over the next decade, the US manufacturing industry is facing a serious crisis, the skills gap. More than 3.5 million jobs will need to be staffed with 2.7 million manufacturing workers retiring. With the skills gap growing larger, it is presenting several groundbreaking manufacturing opportunities.

With 40% of the students who begin a 4 year college program not finishing, and the mounting college debt crisis, it is prime time for our society to start embracing the value of vocational education.  We have spent a generation telling our children that everyone should go to college…..that only a college...Read more

Every Day Should Be Manufacturing Day

american manufacturing

This past October 7th was National Manufacturing Day, 2016.   A day set aside as a celebration of modern manufacturing, meant to inspire the next generation of manufacturers.  Although Manufacturing Day officially occurs on the first Friday of October, I think that every day should be National Manufacturing Day.

Do you remember when you had shop class in Jr. High or High school?  It was a chance to work with your hands and create something.  And, it was a break from abstract book study and allowed you to work with materials and think outside the box.  It also showed kids how an idea could become a commodity they could sell, and...Read more

Perception is Reality when it comes to Manufacturing Quality


perception

Modern manufacturing has come a long way in employing rigorous quality initiatives, but when a defective part slips past the quality initiatives, customer perception can make the situation go from bad to worse very quickly.

It isn’t always easy to get quality right given the current manufacturing environment. Shorter delivery times, increasing competition and elevated customer expectations; it is no wonder that quality is once again front and center.

Customer expectations matter, more so than ever. The new view of quality has expanded. Quality has always had two sides one could argue: actual quality and perceived quality. Often the latter takes longer to...Read more

Customer Service is important for all Departments

Customer-service

In today’s social media environment, an organization needs to include in their mission statement that all who work for the company are a part of their customer service team. Every department and every person should understand how they are serving the customer, or servicing someone who is serving customers.

We are all aware of the critical nature of customer service. Customer service is important for all departments, and should not be limited to one department. In our business, our core customer service department often needs the help of other departments. Unless other departments realize the significance of customer service, it would be tough for them to provide the...Read more

6 Time Management Tips for a Growing Company

bigstock-Time-Management-Diagram-38050528

In today’s workplace, there is more demand on us than ever before. We have to accomplish more in less time, with fewer resources. This puts a lot of pressure on us to be able to manage our time more efficiently so we can get more done, be less stressed and have a feeling of accomplishment. If we aren’t doing a great job of managing our time, then we probably aren’t able to deliver projects on time. In order to help us better manage your time, here are six valuable tips below:

1. Start with a list of easy tasks that can be completed quickly. By organizing a list of easier tasks first, you can get the smaller projects out of the way and...Read more
