S.B.Weston Ltd. Plastic Injection Moulding Specialists

Manufacturing

S.B.Weston Ltd is equipped with a range of electro-hydraulic Demag plastic injection moulding machines. Our machines are NC controlled allowing precise adjustments to the manufacturing process, necessary when moulding consistent quality products.

We have a range of machine sizes enabling us to react quickly to clients orders whilst maintaining constant production of our Weston Boxes. View our plant list for full details.

Specialist Staff

Setters – S.B.Weston Ltd. employ a team of trained machine setters who fully utilise the NC technology available on our Demag machines. Our setters are responsible for closely monitoring the performance of your mould from its initial trial right through to its final production run, making the necessary decisions and modifications to the production process to ensure that your tool runs at optimum efficiency, with the correct temperatures, speeds and pressures maintained over the production cycle.

Maintenance – We service our machines regularly to ensure their optimum performance. A team of qualified Demag technicians perform all necessary repairs and major works, whilst our setters deal with replenishing consumables such as hydraulic oils, grease and lubes.

Material Selection

Our in depth knowledge of  plastics enables us to recommended a material perfectly suited to your job. Required material properties often include strength, impact resistance, flexibility or temperature resistance, all of which can be catered for. If necessary we will test run your product in a number of materials to determine which is the most suitable for the final production run.

Health & Safety

Auto-stop devices are installed on all our machines. Guarding is always present and will shut the machine down if removed or tampered with. Our staff are always trained to understand the potential dangers of the process if health & safety measures are disregarded.

Environmental Impact

We have the facilities on-site to recycle all the plastic scrap we produce and feed it straight back into our processes. All Weston Boxes are manufactured in recyclable polypropylene minimizing the effect of S.B.Weston Ltd’s environmental impact.

Quality Control

We deliver optimum quality mouldings across your entire production run as standard. Quality control checks will take place to ensure you get the exact spec on the mouldings you have ordered.

Machining / Assembly

We regularly perform additional machining / assembly tasks. From simple separation or assembly of multiple parts through to more complex actions such as heat insertions, printing – using hot foil techniques or jigging to set mouldings at a particular shape. We will always look to employ the most efficient methods of production, streamlining so as to minimise the amount of time and labour required and as a result,  keeping the cost to you as low as possible.

Finishing / Packing

If required, we can take care of any finishing / packing that your job reqiures. We are regularly supplied packaging for injection moulded products which we assemble, pack and palletise at the time of production. This can be massively cost effective with mouldings being packed and palletised with in the machine cycle ready to go out of the door to your customers.

S.B.Weston Ltd. Plastic Injection Moulding Specialists. Est 1948.

1940’s

The plastics industry expanded rapidly after World War II which created a huge demand for inexpensive, mass-produced products. Selwyn Weston, founder of S.B.Weston Ltd. seized upon this new market opportunity in 1948, establishing the company’s first mould shop in Teddington, West London.

1950’s

S.B.Weston Ltd. found its niche manufacturing for pharmaceutical clients – in particular ICI, manufacturing agricultural dispensing pumps of Selwyn’s design.

As the plastics industry and its technologies evolved, so S.B.Weston Ltd’s collective experience grew. The company went from solely producing dispensing pumps on to combs, badges and, over the decades, a vast array of products for industries including the medical, consumer products, toys, plumbing, packaging, and construction.

1960/70/80’s

Selwyn’s son Tony Weston joined the company in 1962 as did David Dodman, and upon Selwyn’s death in 1967 they took over the business and maintained its steady success over the next 30 years.

1990’s

The company changed premises settling on Platts Eyot, an island on the Thames, where they survived the recession of the early 90’s and emerged with Reid Weston, Selwyn’s grandson as the managing director.

One of Reid’s first moves was the implementation of the first of our box tools – the Business Card Box. This product has since become the company’s key trade item and the starting block for our current range of boxes, now available in our shop.

2000’s

As well as the Weston Boxes range  and many other trade moulding contracts, S.B.Weston also became involved in producing vacuum formed interior modification parts for luxury cars. The parts, designed by Tony Weston, required expert design, prototyping and execution to integrate with the luxury interiors of the vehicles and due to the unit requirement often being low, vacuum forming was often used as a cheaper alternative to injection moulding.

In 2009 S.B.Weston Ltd. is outgrowing its premises in Sunbury-on-Thames, running 12 NC controlled Demag machines with robotic automation implemented on many production lines.

We now manufacture our Weston Boxes through 24 hour shifts from Monday to Friday to meet demand and despite the recession have a busy design / tool building department with new clients and projects emerging frequently.

Essentially the principal of what S.B.Weston Ltd does is still the same today as it was for Selwyn Weston back in 1948. It is simply the technology we now use to design, manufacture, monitor, maintain and streamline the injection mouding process that has evolved.

S.B.Weston Ltd. is a plastic injection moulding business offering a design and production service to clients. This ‘trade’ moulding is currently 30% of our business.

We also design, manufacture and distribute our own products. Our Weston Boxes have now sold over 45 million units. These products account for approximately 70% of our business.

Clients

S.B.Weston has longstanding relationships with many of its trade clients. We are able to provide a personal service, and pride ourselves on good relations with our clients for whom we produce millions of  ‘trade’ mouldings a year. Many of our clients are prefer UK manufacturing given the advantages for them in terms of ease of communication, the obvious shipping and logistical benifits and, we believe, the superior quality mouldings.

History

S.B.Weston Ltd was established in 1948 by Selwyn Buyers Weston, the grandfather of current manager Reid Weston, read more about the company history here…
