Factory Relocations Check List

Factory relocations are unfortunately common in today`s manufacturing world. From my personal experience I dare to state that such projects never deliver results as scheduled and in some cases even fail entirely. Here are some essential hints to avoid the most frequent mistakes. Please also check out the links below (my personal and constantly updated …

Why synchronized manufacturing is key to short lead times

Synchronized manufacturing means that all machines in a process run at (almost) same speed. A disbalance, bottle neck or damage will be noticed immediately and due to its influence on the whole chain : be fixed.Most bottle necks remain unseen due to the fact that heaps of inventory / buffers are covering up any malfunction. …

Saving energy and time in steam rubber vulcanisation

Rubber vulcanisation is a high energy process. The consumption of fossil energy carriers is gaining relevance in the overall cost structure plus in environmental aspects. Among the currently available technologies steam curing is one of the oldest but still very efficient and dominating when it comes to mandrel – based hose production. Set – up· …

How poor project management can lead to unexpected future losses

The world of mass production is tough and competitive. Capacities / head count have been reduced to the minimum. In addition, I am observing an increasing lack of qualification / technical expertise. One of my services is to improve existing production processes – or straight forward, cut cost. It is surprising, how daily routine is …

Selecting the right rubber compound

Rubber products are often a cheap commodity. Many describe it by colour and maybe Shore hardness. The failure of a rubber part may lead to unexpected, even lethal consequences. These are a few factors to be considered when choosing the correct compound: Medium The medium and its pressure defines the choice of polymer. Each polymer …

7 keys to perfect lathe cutting of rubber gaskets

Rubber compound High X linking density Good ratio between filler and plastisizer High tear resistance Blade Hard surface, treated or Tungsten Carbide Fine grains for perfect surface Slim (asymmetric cutting angle) Circular for best surface, pin ended for high speed Lubricant Low friction Low viscosity (can be even compressed air) Environment friendly Machine Precise Solid, …

Why are some enterprises struggling on their journey towards a sustainable and lean organisation?

The Toyota Production System or in general terms Lean Mangement is commonly known and an industrial standard. But too often that refers to the visual impression. Scratching that surface the results underneath in terms of improvement remain disappointing with respect to savings, quality, growth etc. Let us turn the 4 principles of Lean upside down: In the quest of quick wins …
