Manufacturer of
precision mould bases, press tool die sets and mould tooling components
for plastic injection moulding toolmakers and industrial engineering manufacturers in South Africa.
The standard guiding system in plastic injection and die casting moulds comprises guide pillars, guide bushes, and tubular dowels, ensuring precise alignment between the fixed and moving halves of the mould base. This high-quality system integrates seamlessly with our cavity plates. Key guiding areas include cavity plate A and B, stripper plates, hot runner plates, and ejector pins, and these components can be customized when ordering the mould base.
Standardized precision guiding elements, like tapered dowel pins and side locks, are also available. UTP Mould & Die offers a large range of UTP standard or DME pillars, bushes, tubular dowels, guided ejectors, dowel pins, drill bushes and related components.
Tapered Interlocks, align the moving half and fixed half of the mould or individual cavities and cores with high precision, reducing lateral shifts and maintaining cavity alignment. They are available in various types of steels and in various hardnesses.
Taper Block Sets usually consist of a block with a tapered surface that mates with a corresponding slot. They provide precise alignment along a specific axis, ensuring the correct positioning of the mould halves or individual components.
Locating Block Sets are typically rectangular or square blocks that fit into corresponding recesses. They ensure correct alignment and positioning by providing a physical stop or locator.
Slide Block Sets allow lateral movement while maintaining alignment, often with a flat mating surface. They facilitate sliding action between the mould halves while keeping them aligned.
Insulation boards are essential in injection moulding as they help manage temperature, prevent heat loss, and improve energy efficiency. By maintaining a stable temperature, they enhance product quality and reduce energy consumption. These boards are placed around the mould walls and base to optimize heat retention and limit heat transfer, leading to benefits such as:
· Faster Cycle Times: Stabilizing temperatures shortens heating and cooling processes.
· Consistent Product Quality: Uniform temperatures reduce defects and improve overall product reliability.
· Cost Savings: Lower energy use decreases operational costs, and fewer defects reduce waste.
UTP Mould & Die offer 3 variations of insulation board blank, fixed half drilled and moving half drilled in all mould base series
I-Mold "molding innovations" stands for intelligent solutions and unique, innovative injection molded products.
The tunnel gate inserts from i-mold are recognized worldwide as innovative products with high cost reducing potential for moldmakers and molders.
By using these inserts, manufacturers can optimize the injection process, reduce defects, and improve the overall functionality and appearance of the moulded parts. When designed and used correctly, they can offer significant advantages, including smoother material flow, better part quality, and reduced gate marks

Additional Features:
UTP's Hot Base Solution is a high-performance mould base platform that combines a standard or custom machined mould base with a Hot Half Hot-Runner System from Heatlock.
It is an individually engineered platform - fully designed to the specifications of the user - and is completely flexible, it can easily be equipped with high-end UTP components and accessories as well as precision inserts manufactured by UTP. Specialty mould base designs can include: side entry, multi-material, high cavitation and stack tooling.
The aim is to free up capacity at tooling suppliers from repetitive work and time-intense catalogue researching. Toolmakers can fully concentration on the detailed cavity and core work and the success of the project.
The new platform allows end users to place stricter manufacturing deadlines on their favorite Toolmaker with confidence in his ability to deliver on time.
UTP's special production department will be pleased to develop and supply customized solutions for you in close cooperation with the Standard Plate and Component range of products, Heatlock Hot Runner Technology and the Custom Mould Bases machining business divisions.
Using the latest scheduling and processing methods, we can offer you prompt support in the event that you are experiencing production bottlenecks or large demands on your tool manufacturing. You will benefit from guaranteed planning, efficient high-quality production with a thorough final inspection.
You can rely on us adhering to agreed delivery dates. UTP is fully dedicated to partner with you from the project initiation stage right through to the implementation and production stage of your moulds and tools.
Your benefits
UTP offers its customers quick and precise deep hole drilling of cooling channels at very competitive prices. Water channels are drilled using single lip gun-drills with internal cooling using oil at 100 bar pressure, ensuring very accurate drilling and straightness of the bores.
As an additional service UTP can also machine the countersunk bores to protect the water connectors and tap the required BSP threads.
