Linking Serious Buyers to the Best Suppliers

Plastic vs Metal – is cost the only consideration?

There will always be an argument for using metal over plastic, which has often been seen by both the engineering fraternity and the general public as a ‘poor cousin’.  However, the field of Plastic Component Design and Production has been evolving in recent years, and should now be viewed as a technical solution that in some cases can out-perform machined or cast metal….

Replacing a worn plasticising screw? Shouldn’t you be upgrading for better productivity!

When you buy a plastic processing machine, the plasticising screw is often supplied with a General Purpose (G.P.) design and nitrided wear resistance. In many cases the OEM won’t have been told you only process particular material grades, and a GP screw provides the biggest processing window across the spectrum of materials.

This design however, will always be a compromise….

Cost over Price – why quality machinery can prove less expensive

We often think that it is better to buy cheaper equipment, making comments such as “The job is simple to run” or “It doesn’t require all the bells & whistles” to justify the decision. In my experience this doesn’t stack up and the more costly brands are often less expensive in the long run.

Specific Gravity – Not that Specific at all. Ignore this blog at your peril!

The definition of ‘Specific’ is clearly defined or identified or a precise detail.  Unfortunately, when it comes to specific gravities for polymers, this definition doesn’t always hold true, so in reality you may just be ‘sticking your finger in the air’………

Re-shoring, fact or fiction?

We all know that in recent years there has been a ‘buzz’ in the general Manufacturing Sector about more product being sourced from within the UK, but what do the actual numbers tell us?

Driverless Cars, Robot servants & All Electric Machines – Why haven’t we all got one?

We all know that All-Electric Injection Moulding Machines are more accurate, use less power and are quieter than hydraulic models.  So what happened to the 2004 predictions of a year on year increase in their usage?

One man’s scrap is another man’s treasure

A PlastikCity customer approached me recently saying he would like to advertise various items from his factory on our website. He knew it was free to advertise so he told his staff to look around the factory and tell him what items were redundant and then put them up on our site.

The process of refurbishing a plasticising screw

Most screws are suitable for a number of refurbishments before the thermal stresses imparted by re-welding could result in weakening the structure of the base metal and lead to subsequent fracture……

Looks like the Hippies were right all along!

A bit like not wearing a seat belt, most of us now feel uncomfortable about not recycling our household waste. Recycling can however be more than a way to appease your guilt as a major consumer (around a tonne of Carbon Dioxide production is saved for every tonne of re-processed material used instead of virgin), it can now also make good business sense.

Can you achieve S.M.E.D. on a budget?

The concept of Single Minute Exchange of Die has been around for a while, but for those of us working with a limited budget or a variety of materials (with different processing temperatures), anything under an hour would be nice!  There are however some relatively inexpensive changes you can make, without having to result to budget-busting auto-tool change systems and magnetic platens….

Has our Building Site now become a City?

The aim was to create a major resource for the plastics sector, one place to find everything you needed.  From time to time, we need to review how we are doing, so for the purposes of this Blog, I have looked at things from the perspective of a new start company looking to develop an idea for a new `widget’ that just happens to be most easily manufactured in plastic.

Are you plasticising your material efficiently, or are you ‘poking it in with a stick!’

Having spent a number of years inspecting worn screw and barrels, I know from experience that people go well beyond ‘a few thou’ of wear before deciding it’s time for a replacement or refurb.  A good setter can often work with little more than a stick rattling around in an oversized tube, but there is always a price to pay……

UK Automotive Suppliers buck the European trend for new robot installations, but we can still do better!

For simpler moulding jobs, the ethos of “gravity is free, why should I buy a robot” still holds true. If, however, any of the following points apply, you should consider de-moulding with a robot.

Was Billy Joel right? Why should you invest in higher quality kit?

If you listen to Billy Joel and agree with his philosophy of, “Don’t waste your money on a new set of speakers, you get more mileage from a cheap pair of sneakers”, then we aren’t on the same page……….

We say we support UK manufacturing – our Moulders have shown their commitment – is it time for YOU to put money where your mouth is?

USA manufacturing is booming and riding the crest of the Re-Shoring wave. But I’m fearful we’re losing steam in the UK………

Used or New? What’s best for your business?

During my career I’ve supplied 100’s of new and used injection moulding machines. Determining what is best for your business depends on many factors but essentially the main considerations should be specification and up time requirements.

What is your REAL scrap rate?

Scrap rates for the injection moulding industry are easy to calculate, but often painful to believe – it is simply the difference in weight between how much plastic you buy in, and the total weight of parts delivered. Typically this is as much as 10%, although when questioned about scrap rates companies reported to us the figures they wanted to talk about – such as “customer reject rates” of 4.5ppm or their “production reject rate” where we heard of 0.001%.  These figures are just self-congratulatory and distorted.

Are we on Foot or Horseback?

After 20 something years in the plastics industry working for one of the larger extruder manufacturers in the world I am beginning to wonder when replacing critical parts like Barrels and Screws, do we look any further than the price?

B2B Directories, SEO, PPC – they’re all after your online marketing spend – But what gets you ‘REAL’ results?

Here I explain why PlastikCity encompasses and beats them all if you are a supplier to the UK plastics industry.

Would we need to be buying in now if we hadn’t started by selling out……

It is fantastic to see UK Manufacturing enjoying a renaissance especially in the Plastic Injection Moulding sector where we have a new buzz word called ‘reshoring’. I can’t help wondering though whether too many businesses were quick to sell out to what was perceived to be the ‘Holy Grail’ in manufacturing in the first place. I wrestle with this question that is rarely asked…
