UHMW Turned

UHMW Turned – Commonly, close tolerance Components are CNC Turned daily. Notably, UHMW, ultra-high molecular weight Polyethylene, is one of the most popular thermoplastics for Industrial applications. Hence, not only does it one of the highest impact strengths of the thermoplastics. Also, is highly resistant to most corrosive Materials and moisture. Lastly, it is highly abrasion-resistant, also, has an extremely low coefficient of friction and is self-lubricating.

UHMW Machined Sheet

UHMW Sheet Machined. While Polyethylene Sheet Machining takes place on 3M x 2M Routing tables. Most noteworthy, is the use of vacuum tables. Hence, able to securely hold the Materials, without the need for clamping. Thus, UHMWPE Sheet is CNC Machined without distorting the form.

Typical applications of PE1000: Including, wear strips, liners to chutes and conveyor belts. Also, aggregate handling, food processing, bottling plants and pharmaceuticals.

Finally, Polyethylene Machined Plastic is available in grades. Which, include HDPE 300, HMWPE 500 and UHMWPE 1000 grade.

UHMW CNC Milling

So, having a large capacity of CNC Milling capabilities, Sentinel Plastics Ltd can draw on many years’ Experience. Thus able, to produce high precision Components. Most important, from high specification Industrial Plastics Material. Read more

UHMW CNC Turning

Again, due to investment and thus using the latest Precision Lathes and technology. Hence, via CNC Plastic Turning, they can produce large or small batch Plastic Turned Parts. Thus, from all the various types of Engineering Industrial Plastics.

CNC UHMW Machining UK. Furthermore, capacity is ever increasing. So, whether your requirement is one off or high batch work. Secondly, lead times kept to a minimum. So, whilst the Company aims for quick turnaround times. Likewise, we maintain, a very low level of customer concerns. Certainly, Quality never compromised. Consequently, these are just some of the reasons many customers constantly return. Finally, Sentinel is where Companies Turn for all their Plastic Machined and Fabricated Part requirements.

Take A Look at Our Main Engineering Plastics Processes

CNC Plastic Machining | Plastic Milling

Plastic Routing | Plastic Turning | Plastic Fabrication

To conclude, the Company established in 1989, Sentinel is an Industrial & Engineering Plastics Machining and Fabrication Company. Ultimately, with a long history and much accumulated knowledge the Company has always moved with the times.

Sentinel Plastics Ltd is a well-established Engineering Plastics Supplier UHMW Machined and Plastic Fabrication Company based in Cradley Heath in the West Midlands. Ultimately, the Company has an already large customer base, which includes many long-term blue-chip customers.

Because it has very low moisture absorption, it is also found in some high demand areas of marine applications. It is sometimes used in some cryogenic Components due to its low operating temperature abilities. Because of its resistance to wear and impact, UHMWPE continues to find increasing Industrial applications, including the automotive and bottling sectors. Since the 1960s, it has also been the most used Material for total joint arthroplasty in orthopaedic and spine implants.

Some Advantages of CNC Machined UHMW

UHMWPE is odourless, tasteless, and nontoxic
Has extremely low moisture absorption
Very low coefficient of friction
Self-lubricating and is highly resistant to abrasion
Very resistant to water, moisture, most chemicals
Resistant to UV radiation, and micro-organisms
UHMWPE only becomes brittle at temperatures below −150 °C.

Some Disadvantages of UHMW

Its melting point is around 130 to 136 °C
Not advisable to use UHMWPE at temperatures exceeding 80 to 100 °C for extended periods of time
UHMWPE will deform continually if the stress is present, an effect known as creep
Maybe not suitable for high load applications.

UHMWPE performance

UHMWPE has an incredible resistance to abrasion and can outperform almost any Engineering Plastic in this regard
It has a very low friction co-efficient and provides a bearing medium that is very free running and exceptionally long lasting
Also, it is resistant to many dilute acids, solvents and cleaning agents
It has a max operating temperature of plus 90°C and a short-term operating temperature of plus 120°C
A very tough Material, with the highest impact strength of any thermoplastic presently made.

UHMWPE also used for

Because UHMWPE has excellent abrasion resistance it is often used for sand, gravel or aggregate process applications. These environments are incredibly harsh on any bearing Material, but UHMWPE is one of the few Engineering Plastics capable of withstanding such punishing abuse.

UHMWPE can also be used for low friction pulleys because of its very low co-efficient provides a bearing medium that is very free running and exceptionally long lasting. It is often found in food production environments where high volumes of containers need to be guided along conveyors or production lines.

More characteristics of UHMWPE

High speed steel tooling is recommended. With, lots of back rake. Also, a generous nose radius. Finally, use caution when Turning UHMWPE . In the main, as the chips will be continuous and tend to wrap around the tooling.

Gluing and bonding

UHMWPE does not absorb water readily, nor wet easily, which makes bonding it to other polymers difficult.

Does UHMWPE have good Wear resistance?
UHMWPE is highly resistant to abrasion, in some forms being 15 times more resistant to abrasion than carbon steel.

Chemical resistance

It is highly resistant to corrosive chemicals except oxidizing acids.

Unique characteristics UHMW

Its coefficient of friction is significantly lower than that of Nylon and Acetal, and is comparable to that of PTFE, or Teflon. Skin does not interact with it strongly, making the surface feel slippery, almost waxy.

Our UHMW Machined capacity includes but is not limited to the following: 8 No CNC Machines which includes Mazak VCN 530C + 5 No XYZ 1020 VMC + 2 Bridgeport’s VMC + 2 ProTurn Lathes + 1 Mazak Mill/Turn.

Ultimately, with its high transparency and smooth surface, Clear Polycarbonate Machining is an attractive Material for a wide range of applications. Thus, offering extreme impact resistance, even at temperatures down to -100°C.importantly. Which, unlike Acrylic, which requires heat to form, Polycarbonate sheets can be CNC Routed and cold bent.

So notably, as a Company, Sentinel Plastics has become synonymous with Polycarbonate Machining and Fabrication. Also, importantly, Polycarbonate is the most popular choice of Plastic. Certainly, when it comes to a requirement of strength and ultimately safety. Furthermore, while in its Sheet form, it is extremely impact resistant. Further, interior applications, up to 6 mm thickness Polycarbonate has a B1 fire protection for classification.

Polycarbonate Applications:

Firstly, many Parts Manufactured by Polycarbonate Machining, are guards, screens and covers. Also. Glazing for commercial business and factories. Plus, Safety doors. Certainly, high usage for sneeze guards, make it a popular Material. Further, widely used for Industrial vehicles and Lamp covers. Also, where a high level of heat is generated, being highly fire-resistant, versions exist for the use in Switch cubicles, electrical equipment.
Furthermore, other uses for Polycarbonate are Trade fair structures and Public buildings. Certainly, within the Industry, the clear Plastic of choice is Polycarbonate. Hence, its popularity and wide use as safety guards.

In addition, UV coating can be applied to the surface of the smooth or textured Polycarbonate sheets. Plus, solid sheets retain their shine with no yellowing, nor change of colour. Also, the positive effect in applying a protective coating, is that you are increasing the resistance to long-term weathering. Thus, provides a long Service life.

Polycarbonate Machining – Parts Available in:

Moreover, Polycarbonate, available in Transparent clear and white translucent. Also, available in bronze, grey, green, blue.

Further,available grades: Polycarbonate Machining

1: Polycarbonate Sheet / FG food grade
2: Solid Polycarbonate Sheet / FR flame retardant
3: Polycarbonate Sheet / NR non reflective
4: Outstanding through reinforced UV protection.
