Tirosh's pattern Tooling design team utilizes the most advanced CAD/CAM Equipment.

The company’s engineers are involved in the entire chain: from participation in customer’s initial design to the finished product.
Expert casting engineers ensure the final part design grants maximum manufacturability and meets the required performances. Results are achieved through concurrent engineering and early involvement on new programs.

The design assistance includes:
• Alloy recommendations
• Conversion of machined items to sand Casting technology
• More "producible" casting design
• Cost effective casting applications

Tirosh has developed pattern tooling capabilities to meet the most stringent requirements from customers.

CNC modeling Dep.
Tirosh experienced CNC modeling department can deal with the most complicated geometric cast shapes. The polyurethane patterns are retrieved directly from customer's 3D CAD files, using advanced rapid four-axis machining centers.

Pattern workshop
In addition to the CNC modeling department, the company operates a conventional pattern workshop, manned with an experienced staff of skilled Pattern Makers.
This department provides in-house capabilities for gating and rigging of pattern equipment, repair and maintenance.

The combination between these two departments ensures flexibility, prompt response and efficiency. Tirosh has managed to dramatically reduce lead time to first article: Average yearly output is one new pattern every 2 days.

Precision Dry Sand casting is a process using chemically bonded sands to produce moulds. It is considered the best choice for applications requiring complex parts, intricate coring, high metallurgic integrity, dimensional accuracy, repeatability and stability.

Maximum Versatility
Due to modern, well equipped dry sand layout, Tirosh can manufacture technologically complex castings of various shapes and size, without any dimensional limitation, ranging from tens of grams up to 1000 Kg and more. The company can handle small series, medium-sized and high volume series.

Tirosh new Heinrich Wagner Sinto automatic moulding line, combined with Eirich Gustav Sand Preparation Plant are among the best of their kind in the world.

Speed: 30 moulds/hour
Moulding box size: 800 x 650 x (250 + 300) mm 

Moulding Line main advantages:
• Designed for jobbing: Short setup time and rapid turnaround increases flexibility and efficiency.
• Versatility: Adaptable for small size jobbing series as well as for high volume long series.
• Cost effectiveness: Due to saving on materials and manpower, Tirosh is able to maintain good cost as well as effective, keeping castings costs relatively low.

Supreme quality: the minimization of dependence on human factor ensures:
• Tighter tolerances
• Better dimensional stability and reputability
• Decreases lead-times and scrap.

The digital dimensional Inspection department is fully equipped with the spear head of Castings and patterns are measured by two layouts of digital Faro Arm Measuring Machines, using CAD to CAD comparison system measuring technology.

Machined parts are inspected using L.K.'s CNC Coordinate Measuring Machine.

The in-house non-destructive tests laboratories enable fast response while developing new prototypes. Tirosh NDT laboratories are NADCAP certified.

• Liquid-penetrant (PT) lab

• Radiographic laboratory (RT) (320 Kvp)

• Boroscopic inspection of long and narrow core passages

The in-house, well equipped metallurgical laboratory carries out chemical analysis using modern optical spectrometer, as well as mechanical properties  tests (tensile and hardness).

Heat Treatment
Tirosh department performs Common heat treatments such as: T6, T5, T7.
Dimensions: up to 1300X1300X1800mm.
The H.T process is NADCAP certified.

Machining Capabilities
Machining department is equipped with state of the art HASS machining centers (1270x660x800 mm), operated by professional team, expertise in complementary machining of aluminum castings.
Tirosh also provides surface treatments, painting and finishing operations as required, through approved Sub-contractors.
