Applications
Pump casing Refurbishment
Pump Casing Reconditioning
Slurry and process pumps operate in extremely harsh conditions. Constant exposure to abrasive media, corrosive fluids, and cavitation gradually erodes pump casings from the inside out—reducing efficiency, increasing energy consumption, and ultimately leading to costly replacements.
Before replacing your casing, consider reconditioning.
Our pump casing reconditioning process begins with professional blasting, stripping the surface down to clean, bare metal and removing all corrosion, scale, and degraded coatings. We then apply a high-performance epoxy coating specifically designed for slurry and wet-service environments. This restores the internal profile of the casing while creating a durable, chemical-resistant barrier against future wear and corrosion.
The result is a fully restored casing that returns to service at a fraction of the cost of a new replacement—while delivering improved protection and extended service life.
This solution is suitable for slurry pumps, process pumps, and water pumps. New casings can also be coated prior to commissioning to maximise first-life performance and durability.
PIercing Punches
Piercing Punch&Custom Tooling
Tooling performance directly impacts your production output, part quality, and bottom line. A punch that dulls prematurely, a die that chips under load, or incorrect clearance geometry matched to your material are not minor issues—they are production problems.
At Rapid Precision Manufacturing, we manufacture precision piercing punches, dies, and custom tooling designed for performance, durability, and consistency.
We work across the full spectrum of tooling materials, including conventional tool steels such as H13, D2, S7, and A2 for standard applications, as well as high-speed steels like M2 and M42 for high-wear and elevated-temperature environments. For the most demanding applications, we offer powder metallurgical (PM) steels, delivering superior wear resistance, toughness, and dimensional stability where conventional grades fall short.
All tooling can be supplied with or without advanced performance coatings. These include PVD coatings such as TiN, TiAlN, and CrN, as well as TD Vanadium Carbide, significantly extending tool life beyond what base materials alone can achieve.
We also provide expert guidance on:
Steel grade selection
Coating specification
Clearance and tooling geometry
All recommendations are tailored to your material type, press tonnage, and production volumes, ensuring optimal performance and maximum tool life.
DTH Saver Subs
Drill String Consumables
Down-the-hole (DTH) drilling is one of the most demanding applications in mining and drilling. Sandy, abrasive formations quickly wear out poorly treated drill string components—driving up replacement costs and reducing productive drilling time.
At Rapid Precision Manufacturing, we manufacture and supply high-quality DTH drilling consumables, including:
Saver subs
Cross-over subs
Stabilizers
All components are engineered to perform reliably in the harshest drilling environments.
Our products are supplied case hardened as standard, providing the surface hardness and core toughness required for demanding drilling conditions—while remaining cost-effective.
For operations requiring superior wear resistance, we offer our Boro-Coat upgrade. This advanced boronizing treatment achieves surface hardness levels of 1500–2000 HV, significantly outperforming conventional case hardening and dramatically extending component life in abrasive conditions.
Whether you need direct replacements or longer-lasting alternatives to your current components, we manufacture to your exact specifications and deliver with lead times that keep your rigs operating without unnecessary downtime.

Tungsten Carbide Sample Crushing Pot
Tungsten Carbide Tooling
Tungsten carbide is not a single material—it is a range of grades engineered with different combinations of hardness, toughness, and wear resistance. Selecting the wrong grade is one of the most common and costly mistakes in tooling. Too hard, and it chips. Too tough, and it wears too quickly.
Getting the grade right from the start is critical—and that is where we add real value.
At Rapid Precision Manufacturing, we supply tungsten carbide in two forms:
Carbide blanks – Ideal for customers with in-house toolrooms who require high-quality raw material for grinding and finishing
Fully finished, precision-machined components – Ground and lapped to your exact dimensional and surface finish requirements, ready for direct installation

Punches and dies
Die inserts
Wire drawing dies
Wear pads
Nozzles
Bushings
Custom profiles
All components are manufactured across a wide range of application-specific carbide grades, ensuring optimal performance in your operating conditions.
Whether your application requires:
Maximum wear resistance for high-volume production
High toughness for impact or interrupted operations
Corrosion resistance for wet or chemical environments
We ensure the correct carbide grade is selected before manufacturing begins, maximizing performance and tool life.
Blanks are supplied in standard and custom dimensions. Finished tooling is manufactured to drawing or sample, with grade selection advisory included as standard.
Plastic Injection Mould
Plactic Moulding
Plastic injection moulding is a precision process where mould surface condition directly affects part quality, cycle time, and tooling longevity. Corrosive out-gassing from certain materials can attack unprotected mould surfaces, while abrasive fillers like glass fibre cause premature wear. Sticky materials and complex geometries also make demoulding difficult and slow.
There is no single coating that solves every problem—the right solution depends on your application, production conditions, and part design. That is exactly how we approach it.
We supply a range of specialist mould coatings tailored to your requirements:
Release coatings (MTC & PTFE) – Ideal for sticky materials and complex geometries, eliminating the need for release agents, reducing cycle times by 15–30%, and improving surface finish
Wear-resistant coatings (Thin Dense Chrome & PVD – TiCN, CrN) – Designed for glass-filled and abrasive materials, combining hardness with excellent release performance
Corrosion-resistant coatings (Electroless Nickel High Phosphorus) – Provides a dense, chemical-resistant barrier for aggressive processing environments, extending mould life significantly
We also manufacture precision mould components in-house, including:
Cores
Pins
Inserts
Bushings
All components can be supplied fully finished and coated, ready for direct installation into your mould base.

Our Coating Solutions`
01
HVoF(Tungsten Carbide)
HVOF (High Velocity Oxy-Fuel) is one of the most advanced and widely specified wear-resistant coating technologies used in industry today. The process propels tungsten carbide particles at supersonic velocities—up to 800 m/s—creating an exceptionally dense, low-porosity coating with outstanding bond strength and hardness.
The result is a surface capable of withstanding severe abrasion, erosion, and sliding wear, significantly extending component service life in demanding environments.
HVOF coatings are highly versatile and can be applied to a wide range of components, including:
Shafts
Pump components
Rolls and cylinders
Valves
Impellers
They are also widely used as a hard chrome replacement, offering superior wear performance without the environmental and health risks associated with hexavalent chromium plating.
We apply HVOF tungsten carbide coatings using WC-Co and WC-Co-Cr powder systems, achieving:
Hardness levels of 1000–1400 HV
Porosity below 1%
All components are precision ground after coating to meet required tolerances and surface finish specifications, and are delivered ready for installation.
02
BoroCoat
When conventional surface treatments like nitriding and carburizing no longer deliver sufficient performance, Boro-Coat provides a superior solution.
Boronizing is a thermo-chemical diffusion process that forms an extremely hard iron boride layer within the surface of the steel substrate, rather than on top of it. This creates a true metallurgical bond, meaning the coating cannot peel, flake, or delaminate under mechanical load or impact—making it one of the most durable surface treatments available for abrasive and high-wear environments.
Boro-Coat achieves surface hardness levels of 1500–2000 HV, significantly outperforming:
Nitriding (700–1200 HV)
Carburizing (550–750 HV)
This results in substantially extended component life in abrasive, sandy, and erosive operating conditions.
The process also introduces minimal distortion, ensuring that tight-tolerance components retain their dimensional integrity—often eliminating the need for post-process grinding.
Boro-Coat is ideally suited for applications involving:
Constant abrasion
Particle erosion
Sliding wear
It is also a cost-effective alternative to HVOF coatings for shaft sleeve applications, delivering comparable service life at a lower cost and with faster turnaround times—without the need for pre-machining or post-grinding.
Typical Applications
Pump shaft sleeves
DTH drilling components (saver subs, cross-over subs, stabilizers)
Wire drawing components
Agricultural wear parts
Forming tools
Any steel component operating in abrasive or erosive environments

Tooling Coatings
Tooling is a major investment. When punches dull prematurely, dies chip under load, or forming tools wear beyond tolerance, the cost shows up in regrinding, replacement tooling, and lost production time.
Applying the right coating to the right tool changes that completely.
At Rapid Precision Manufacturing, we apply specialist hard coatings to:
Punches and dies
Forming tools
Mould components
Cutting tools
Precision tooling
These coatings extend service life, reduce friction, improve release, and in many cases eliminate the need for lubrication.
Our coating solutions include both PVD (Physical Vapour Deposition) and TD (Thermo-reactive Diffusion) technologies, allowing us to match the coating precisely to your tooling, material, and operating conditions.
PVD Coatings
PVD coatings deposit ultra-hard ceramic layers such as TiN, TiAlN, TiCN, CrN, and AlTiN at thicknesses of 1–5 microns, with no dimensional change to the tool.
Hardness exceeding 3000 HV
Ideal for tight-tolerance tooling
Excellent wear resistance and reduced friction
Common applications include cutting tools, punches, dies, and mould components.
TD (Vanadium Carbide) Coating
TD coating forms a vanadium carbide layer within the tool surface through a diffusion process, creating a metallurgically bonded coating that will not peel or delaminate.
Hardness of 2500–3800 HV
Exceptional resistance to wear and galling
Ideal for extreme-duty tooling
Best suited for wire drawing dies, cold forming tools, and high-wear mould components.
