Numac Delivers Whatever the Project

August 2nd, 2016
Share this article:

Numac Engineering is continually growing and developing, investing in the latest technology to stay one step ahead of industry needs. Yet the service the team offers remains as personalised to every individual client and project as on the day Numac welcomed its first customer 25 years ago.

nov-email-1Although the spectrum of what Numac can provide has never been greater, whatever a client’s requirements – whatever the material, the size of the components or the volume of the batch wanted – Numac can deliver a high-quality tailored solution.

Whatever the material

As well as extensive experience and knowledge of using common materials such as stainless steel of all grades, Numac has increasingly been working with clients to produce specialist, low-volume components in highly exotic materials, including titanium, Hastelloy and nickel alloys such as Incoloy. Given Numac’s highly successful track record with these projects, the team is confident that if anyone can machine it, they can – and they would be delighted to assist with requests for components in any material of this nature.

Leading technology

Requirements for specialist projects of this nature inherently call for manufacturing in low volumes, sometimes only one or two pieces. The ability to deliver small batches of this kind demands high levels of quality control, skill and efficiency. Numac has already invested heavily in the technology, specifically CNC equipment and machine tools from the globally renowned Mazak brand, and the development of production techniques to ensure this is achieved every time. Of course, batches of all sizes, including very high volumes, benefit from these state-of-the-art facilities and ultra-efficient processes.

nov-email-2Large or small

Numac’s superior machine range allows the creation of components in the full size spectrum from just 6mm to 600mm, and anywhere in between.

Components manufactured by Numac are frequently deployed in very challenging, hostile environments, such as in sub-sea applications in the oil and gas industry. Failure or damage under these circumstances can be catastrophic as well as extremely costly, so quality is always at the forefront of Numac’s work, whatever field the project is destined for. Numac is certified to ISO9001:2008 and exacting standards remain paramount within every individual job, on any scale.

Tailored service

Numac is proud to have the processes, equipment and expertise to be able to offer a personalised and flexible service whilst completing all projects at the same optimum level. Depending on what is needed, the team can take total responsibility for the manufacture of components, work alongside the client to establish and deliver to customised specifications, and work with specially selected expert sub-contractors to manage an entire project in the most efficient way possible.

Flexible Arrangements – Maximises Supply Chain Efficiency

Using world class engineering skills to deliver top quality components for clients is central to the culture at Numac Engineering.

Numac also focus on developing a lean and flexible manufacturing process, and for one customer this allowed them to cut costs by outsourcing the uncertainties in their supply chain.

The customer (a major player in the hydraulics industry) needed to be able to guarantee the supply of components without the need to tool up internally for every eventuality. They also needed to do this without any compromise to the quality and efficiency of their supply chain.

Offering the customer the facility to buy a fixed number of hours on NUMAC Machines, rather than the more normal sub contract arrangement to supply a number of components at a fixed unit price, delivered this flexibility. Guaranteeing capacity as and when it was needed.

So how does it work?

On a weekly basis the customer buys a set number of hours from Numac.

On a daily basis, Numac visits the customer to collect any required work. This is then processed within 48hrs and returned to the customer.

It’s that simple!

The benefit to the customer

The result is that the customer knows that any components needing machining will be available as finished items within 48 hrs, irrespective of their own internal capacity.

Furthermore the number of hours required can be forecast & bought as needed at short notice.

“Although this in not the way we have worked in the past, it meets the customers needs better than traditional sub contract arrangements, and thus we are happy to oblige” explained Andy McLaren at Numac. “Our skill is in delivering high quality components efficiently & cost effectively. We are happy to apply this skill in the manner most suited to an individual customer requirement.”

Numac lends expertise to R&D process for optimum results

operatorNumac has recently completed successful final testing of a brand-new component that the team has helped to develop at every step since the early drawings.

The client turned to Numac when other suppliers were unable to deliver the desired improvements to the existing product. The goal was to create an Inconel seal ring for a sub-sea Christmas tree in place of the composite versions already in use, with the aim of increasing their longevity and cutting down on the maintenance required.

The challenge

Many of the components manufactured by Numac are intended to be deployed in highly challenging, hostile environments, such as within sub-sea applications in the oil and gas industry. The company understands how catastrophic, as well as costly, failure or damage under these circumstances can be, and has the experience and state-of-the-art equipment to ensure optimum reliability and performance.

In this case, the involvement of Numac from the start meant that not only was the end product of the highest possible quality – drawing on the specialist expertise of both parties – but the process was streamlined for maximum efficiency with no waste of time or money on unnecessary discussions, amendments and delays.

Efficiency without compromise

The drawings were supplied to Numac for the company’s insights on manufacturing issues ahead of work on the prototype beginning. Once complete, the prototype was returned to the customer for testing and verification of exact measurements. Further machining to meet these was followed by additional rigorous testing by the client. When all standards were absolutely satisfied, Numac applied the final coating and returned the new product to the customer for one last round of testing.

At every stage, the focus was maintained on efficient manufacturing without compromise on the precision needed to meet the product specifications. This was achieved throughout the research and development of the seal ring because of the shared knowledge and close working relationship between the customer and the team at Numac.

The Challenge

sub-sea_1Numac’s client (a major player in the oil & gas industry) had a requirement for a series of components for use on sub-sea hydraulic systems.

The components which were significantly smaller than many of the items handled by Numac still needed to be manufactured to exacting standards. Add to this the fact that the items were manufactured from Inconel, and would be required from 1 offs through to batches of multiple hundreds, has the project calling on all Numac’s manufacturing and process management skills.

The Process

Numac Engineering was happy to take on this responsibility, and undertook the manufacturing of the components .

The range components consisting of ten different parts require precision machining and finishing to the highest standards to allow the onsite butt welding of the components into the wider hydraulic systems on site.

Given the harsh environments into which the components were being installed, joints & weld faces needed to be machined to exacting standards in order to ensure that onsite welding processes  were trouble free when the components are installed.

sub-sea_2The result

Deliveries of the families of parts commenced earlier this summer, and the client is now able to call off batches as they require for delivery across the globe. With the flexibility of supply being handled by Numac Engineering

Furthermore, Numac’s experience and quality control expertise ensured that the quality of the finished item was first class, whilst at the same time ensuring that components were available as and when the client required them thus simplifying the supply process.

Following the first deliveries, the client has now made commitments to deliveries into 2014 and beyond.

Our philosophy is simple:

“In these prolonged difficult economic times, Numac continues to succeed and invest in the latest technology and in the skills of our staff to ensure we provide our customers with the highest quality of product. With experienced staff working around the clock, customer requirements are quickly met with efficiency. This case demonstrates that this philosophy delivers real benefits to our customers.”

A Case Study – Well Head Connector Pin for the Oil & Gas Industry

May 9th, 2013
Share this article:

challengeThe Challenge
Numac’s client (a major player in the oil & gas industry) had a requirement for a series of well head connector pins for use on wells across the globe.

The pin needed to be manufactured to exacting standards & capable of withstanding the harsh environments associated with the industry. Furthermore although the manufacture of the component required a number of specialist manufacturing processes, the client wanted one organisation to take total responsibility for the manufacturing process from beginning to end.

The Process
Numac Engineering was happy to take on this responsibility, and undertook the manufacturing of the component as follows:

Starting with an AISI 4140 Chromium-Molybdenum low alloy steel billet the manufacturing process had 6 key stages:

1.    Initial machining of the component
2.    Application of a Hard Chrome Plate – External Process
3.    Grinding
4.    Application of a phosphate coating – External Process
5.    Finishing
6.    Quality Checks/Packaging

Stages 1, 3, 5 and 6 are carried out directly by Numac, with stages 2 and 4 being outsourced to specialist partners, with Numac taking responsibility for managing the entire process including the external operations, and managing the quality throughout.

The Result
By subcontracting specialist processes to trusted partners, Numac are able to ensure that all steps in the process were carried out by experts, whilst at the same time ensuring that the efficiency of the process was maximised.

Furthermore, Numac’s experience and quality control expertise ensured that this approach did not compromise the quality of the finished item whilst at the same time simplifying the buying process for their client by offering only one point of contact in the supply chain.

Following the first delivery late last year, this approach and the resulting high quality of the components delivered has given the client the confidence to commit to an order for regular deliveries until 2015.



Our philosophy is simple:

“In these prolonged difficult economic times, Numac continues to succeed and invest in the latest technology and in the skills of our staff to ensure we provide our customers with the highest quality of product. With experienced staff working around the clock, customer requirements are quickly met with efficiency. This case demonstrates that this philosophy delivers real benefits to our customers.”

Anyone who has been following Numac Engineering’s progress recently will be in no doubt of their commitment to investment for the future, with over £0.5 million invested in new machinery & inspection technologies over the past 2 years!

But they also recognise that technology is only part of the equation, being useless if the company does not have the skills to make efficient use of it. With this in mind, apprenticeships have always played a big part in the HR programme within Numac.

The company has had some great apprentices over the years, with this year’s apprentice Tom Bullock receiving the Programme LED Apprentice award from Tameside College.

“As an engineer myself I have always recognised the importance of a skilled workforce.” Explains Andy McLaren MD at Numac. “These skills take time to develop so apprenticeships are the perfect tool to deliver them. It is a credit to Tom that he has received this award, and our customers will definitely benefit from his skills as Tom’s career develops.”

Numac run a 5 year apprenticeship in partnership with Skills Solutions and Tameside College. At the end of this, the majority of apprentices are offered a permanent contract with the company.

“I have lost count of the members of our workforce who joined us as an apprentice, but it has proved an excellent way of creating a strong and stable team within the organisation.” continues Andy.

The company’s order book demonstrates that this strength and stability has not gone un-noticed by Numac’s customers, many of whom are world leaders in the field of oil & gas engineering, resulting in a record order book currently stretching out to 2015.

Our philosophy is simple:

“Long term planning & investment in both skills and technology are key to delivering results. Our commitment to skills development, coupled with strategic long term investment plans, mean that we are perfectly positioned to provide our customers with the highest quality of product, both now and into the future. With experienced staff working around the clock, customer requirements are quickly met with efficiency.”

Quality & efficiency are two central priorities when it comes to Numac’s shop floor operations. That is why the decision to invest in the new Venture Plus Vision System was an easy one to make.

The new system which will enhance Numac’s testing & inspection facilities, uses a state of the art multi sensing vision system to perform highly accurate (down to 0.5µ) quality inspections .

Furthermore, because the Venture Plus is CNC controlled, it’s activity is highly automated, thus freeing up the operator to liaise more closely with the shop floor, ensuring a more streamlined & efficient process.

“We are delighted with this new addition to our facility  as in addition to improving the efficiency of our processes, it also delivers direct benefits to customers” Explains Andy McLaren MD at Numac Engineering .

Key customer benefits delivered by the Baty Venture Plus Vision System are:

  • Enhanced accuracy on inspection down to 0.5µ
  • Improved dimensional reporting
  • Availability of full dimensional drawings of the actual part being analysed


“We are particularly excited about the new facility to offer customers full dimensional drawings of the actual part being manufactured. This will now be available on request to all customers” continues Andy “Thus allowing decisions to be made based on 100% accurate information”

A further benefit of the investment is to improve the efficiency of highly skilled shop floor engineers.

In the current climate, where recruiting skilled employees is a challenge, the new inspection systems will result in efficiency savings equivalent to an additional machine operator, further enhancing our ability to deliver for our clients.
