Ingramatic | Sacma Group
INGRAMATIC has many years of experience in the production of machines for the thread rolling of screws and bolts. It started business in 1966 and has since then produced and distributed over 3000 thread rolling machines worldwide becoming a market leader not only in Italy but around the World. In 2006, a new m² plant was built in Castelnuovo Scrivia. This new facility marked a turning point in terms of logistics, organization and efficiency towards meeting new goals and markets.
INGRAMATIC has been part of the SACMA Group since 2004 creating a unique technical, productive and commercial alliance.
The INGRAMATIC Thread Rollers and products complement the SACMA production range and can be used along with progressive headers for the thread rolling of highstrength screws, bolts and special fasteners.

Thread Rolling Center
Flexibility in production has become an essential parameter in conquering new markets. It is important to produce highly customized machines according to the customer needs and strategies. Ingramatic presents several solutions, such as: THREAD ROLLING CENTRE; which demonstrates machine flexibility, directly targeting dynamic factories present in different markets with only one production mean, the capability to thread parts after heat treatment, special parts (grooves) and studs.
For this achievement Ingramatic incorporates different feeding systems within the same machine, in order to enable it to produce both bolts and studs. The machine includes both rails and vibratory feeder for screws and a tube device feeding unthreaded studs into the introduction area. For the production of studs, the THREAD Rolling Centre utilizes a feeding system of proven reliability.
The blanks are positioned in front of the starter finger by a tube. A pneumatic separation device ensures the correct part supply into the work area. To ensure the correct orientation of the parts we have two possible solutions:
- the optimal solution is the connection of the Thread Roller directly to the Header; transferring the forged part directly to the Thread Rolling machine through the connecting tube.
- the second solution involves a vibratory or vertical feeding system, depending upon the length of the parts, with a mechanical selection device incorporating a digital camera.
The system with a digital camera allows the control of individual parts, these parts pass on a conveyor for a control ensuring a reliable orientation. If a part is not correctly orientated, a positioning station corrects its orientation before its introduction into the tube. This device allows high production speeds even if the Thread Roller is not directly connected to the Header. The “P” or “VP” machines allow very high quality production, together with high production speeds. Download Ingramatic Thread Rolling Guide.

High Speed and Reliability – The use of optimal high tensile materials made with the proper heat treatment specifications and ultra-precision surface finishes makes an Ingramatic the most precise, the most reliable, the most productive and lowest operating cost machine available on the market.
Flexibility – Single Starter unit with servomotor. Available options include the new Washer Assemby unit and Stud Feeding systems.
Rigid – The new designed frame, optimized by using FEM software, uses a “C” shaped stiffener that is specifically designed to counter the load stresses caused by thread rolling of heat treated parts and special profiles; providing precise and repeatable setups, consistent part quality and improve die life.
User Friendly / Ergonomic – Touch screen controls for all machine functions, safeties and information. Easy access for setup and maintenance.
Quick Set-up – Motorized adjustment of the feed rails and bowl feeder. Servomotor adjustment for the starter finger and the die match. Hydraulic clamping of the of the drive unit and stationary die position. Load monitor with computerized die match setting. Quick diameter change spacer set. New washer assembly unit with Quick Tool Change.
Simple to use for the operator – Electronic handwheel can be used for precise jog control for easy and quick setups and for all machine adjustments – die match – feed rail position – starter unit, eliminating the use of hand tools.
Washer Unit
THE NEW QTC WASHER ASSEMBLY UNIT ON ITS I-THREAD ROLLING MACHINES.
INGRAMATIC is a first class company for designing and manufacturing thread rolling machines with washer assembly units. After the New Motorized Die match and the New Introduction System with single or double starter units activated by servomotors, the R&D introduces a unique solution for parts needed to be assembled with one or two washers. Ingramatic equips its machines with extremely compact and flexible assembly units. Without compromising thread rolling machine’s reliability and productivity, these devices can be used to assembly different types of washers (flat, chamfered, conical, waved, toothed, split, etc.) with a wide range of blank diameters and lengths.
For high speed production of small screws and bolts, Ingramatic can supply a system for automatic loading of washers and blanks into the respective feed vibrators, making the threader a really independent production line.
The new QTC Washer Assembly Unit is now available for the most exigent users. Ingramatic can supply as option a new system in order to save time during the production changeover. This QTC Washer Assembly Unit allows the operator to set up the tools in the tool room and to save time on board of the machine.
The sensor control system ensures that every screw and bolt sent to the thread rolling machine have washers and ensures that those without washers continue circulating until they are properly assembled. All adjustments are motorized and saved into the PLC allowing the operators to restart a production within few minutes.
The Ingramatic Thread Rollers and products complete the SACMA production range and can be used along with progressive headers for the thread rolling of high strength screws, bolts and special fasteners with one or two washers.
Pointing Machine
Many screws or bolts require a chamfer or a point shape before thread rolling. There are many different types of points that can be made easily and at low cost by cutting rather than using complex and more expensive forming tooling.
The INGRAMATIC pointing unit spindle is mounted on a motorized slide so that it can easily be set on the correct position for the different lengths of blanks. This position can be memorized to speed up set up times. The blank is first placed between two fingers which clamp the part and lower it to the pointing tools, where the point is cut. The scraps are ejected with the coolant and collected in a special container where the liquid is filtered and recirculated. According to customer preferences, the pointing unit can be a standalone machine or a work unit integrated with the thread rolling machine to point the parts before thread rolling using the same assembly unit.
Innovative solutions: standalone pointing unit or integrated pointing system. Make your choice…
