When using cold heading, material selection for a cold-formed part is very important. High quality material is purchased per cold heading raw material specifications with strict requirements placed on vendors for material chemistry and surface defects. Initial cost for raw material may be greater, but the added expense up front is worth eliminating quality problems later on.
There are two ways to make a bolt or screw out of a piece of round stock. First, there is screw machining, that cuts excess metal away from a piece of bar stock until what remains is the shape you want. Thesefasteners start out with a bar stock size equal to the largest diameter of the fastener being made. This process produces a fastener with scrap material left over. The second method, cold heading, forces a piece of wire stock into the desired shape without removing any metal. When finished, the fastener will be produced without wasted material.
One goal at Bossard is to help our customers achieve lean manufacturing. There are many principles that need to be considered when looking to improve manufacturing in order to operate lean. All principles are important and must be understood by everyone involved in the manufacturing process in order to effectively implement lean manufacturing practices. When starting to look at how you can operate lean, there are a few basic principles to examine first. (more…)
The world around us is all held together by screws, nuts and bolts. Bossard works hard to provide fastening solutions and superior inventory management solutions.
Working hard to provide our customers with a wide range of products and solutions, it is an honor to be recognized for excellence in what we do. Recently, Grundfos named Bossard one of their Best Performance Suppliers for 2013.
Managing logistic solutions and supply management is an often overlooked area in many industries where time and money can be saved and waste can be cut down. Bossard is a pioneer when it comes to logistics solutions. We offer solutions that focus on the supply chain and on-site operation support.
If you are looking to increase productivity in any application or industry, the best place to start is to examine total cost of ownership of fasteners in use. By reducing the unseen costs (which can represent up to 85% of the total in place cost) a dramatic cost savings will occur during the entire life of the product model.
When looking to improve productivity and control or possibly lower cost, the total in place cost must be evaluated.
The 85/15 theory can be applied to any situation. The question may change from “where do I spend most of my time?” in regards to the tasks at hand to “where do I spend most of my revenue in regards to the task of generating a profit?”
There are many different quality requirements that our team takes into account before we recommend a fastener for a particular product. The first factor is the life expectancy of the product in which it will be used. It is important that the fasteners will hold up as long as the product in order to avoid productivity pitfalls with continuous replacements. Next, we examine finish requirements. Is there a corrosion factor at work? Material requirements are also closely considered because fastener strength is important. Temperature extremes are also a crucial component of material requirements because severe heat or cold can affect fastener performance. Also, will the joint be exposed to a corrosive environment? The more knowledge we have about what the fastener will have to withstand, the better position we’re in to make a suitable recommendation. (more…)
