Insight

SACMA Group supplies innovative equipment that is productive, efficient, and reliable, for manufacturers of special formed parts, special fasteners, and all types of bolts and screws – used in a variety of different industrial sectors.

SACMA Group points out that both SACMA and Ingramatic machines are highly appreciated by customers, due to their good design and build, power, as well as their ability to quickly and reliably produce special or standard parts, long or short, whilst generating low cost production.

Since 1939, SACMA Limbiate SpA has provided high-quality forming machinery to every part of the world – manufacturing and assembling reliable cold and warm formers and providing, the company reports, more new machines per year than any other premium manufacturer.

SACMA formers from SP160 to SP670 are available in several models up to 33mm diameter cut-off capacity and feature the most advanced controls and systems for forming net and near net shapes with consistent and repeatable tolerances up to 350ppm.

Unique features of SACMA’s machines include:

• One-piece cast bed frames and heading slides with forged crankshafts for maximum rigidity and stability for the tooling and machine components – giving precise part forming and reduced maintenance cost.
• A desmodrive transfer design that SACMA says is the most reliable, accurate and lowest maintenance cost transfer available. The transfer provides the greatest flexibility of any design, allowing the users the ability to form a wide range of part shapes and the possibility to actually form nut and bolt shapes on the same machine. There are no springs or liners in the transfer system, eliminating the maintenance and cost associated with other transfers.
• A computerised S-Feed electronic feeding system, which provides the operator with the most accurate and precise cut-off volume control. There are no springs, levers, clutches, bushing or pins that can wear to cause gradual loss of feeding precision or the need for maintenance – required by some other systems.
• A full range of options are available including the electronic handwheel jog control, which provides precise slow motion control of the machine movement for obtaining extremely accurate set-ups for closer part tolerances and reduced set-up times.

One-shot process from wire to finished parts
In addition to its progressive header models, SACMA also offers combined headers that form, cut the point, and roll the thread, to make a complete fastener on the same machine – eliminating the extra handling and cost of separate operations. SP18 to SP59 models are available in several configurations to provide the most flexibility for threaded fastener production from M4 to M24.

This technology is the more effective solution for high productivity requirements, by utilising seamless workflow for the heading, pointing and threading of standard and special fasteners. It provides complete control to assure quality and to minimise manpower for the highest production efficiency. The process costs are significantly reduced by requiring less floor space and lower energy consumption and by reducing the internal material handling. A complete headed, pointed and threaded fastener is made on every machine stroke up to 350ppm.

For special materials, SACMA offers the only production proven, fully integrated warm former available for the efficient production of high-tensile strength materials like those used in aerospace and high temperature applications. Combining the state of the art controls and automatic support systems, with the advanced induction heating units, heats the wire to the centre to give very precise control of the material deformation for forming consistent near net part shapes with repeatable tolerances.

SACMA has also extended the product line by introducing the new 6 die combined headers models SP59 and SP59-C – 24mm wire cut-off, DKO 180mm and 110mm – meeting the demand of the automotive industry to produce ever more complicated threaded parts.

Flat die thread rollers
Ingramatic SpA, a division of the SACMA Group, offers a full range of flat die thread rollers (RP020 – W000/TR00 to RP920 – W70/TR9) which are recognised throughout the world for their precision, advanced features, and capabilities, along with the legendary reliability of all SACMA products.

Ingramatic points out that the I-Thread line features the strongest bedframe design, drive units with high precision planetary gearbox and clutch/brake systems to give the highest possible torque and stability for rolling all types of materials and tensile strengths. Combining this with the single starter system, with torque motor control on the size W20/TR4 and smaller or the double starter system with servo motor systems on the larger models, provides very precise feed control for accurate and consistent part starting and close, as well as repeatable part tolerances at the maximum possible production speeds – even when rolling parts after heat treatment. Ingramatic points out that users are reporting significant die life increases due to the precision and stability of its Ingramatic thread rollers.

The I-Thread line is very easy and quick to set-up through the touch screen controls; motorised adjustments such as the die match; and the electronic handwheel controller, which allows lesser experienced operators to quickly become proficient in running quality production.

All I-Thread models are available to have one or two integrated washer assembly systems that feature quick changeovers and control from the touch screen. The washer assembly systems are motorised for height control and for bypassing when running parts without washers. A vision controlled stud feeding system is also available for obtaining maximum production rates for rolling headless studs.

Ingramatic has also extended its product line with the smallest threader inspired by the I-Thread concept – the model RP020 for the high-speed production of very precise miniature screws. The machine is equipped with the latest technologies available, including an innovative tool holder, an introduction system driven by a torque motor, and a slide running on linear guides (with ball circulation skates) – in order to ensure high accuracy for the rolling operation. The machine is equipped with the same advanced functions of the I-Thread machines, like the self-learning adjustments of the starter unit, the frame made of spheroidal cast iron and the SC-Matic interface for the fully motorised adjustments.

The design and features of the I-Thread line give the customers the capacity to run the widest range of parts for a given die size at the highest possible production speeds, efficiencies and die life. The machines are simple to set-up and operate but are designed to provide many years of high-quality production with the lowest possible production cost.

Years of reliable production
The modular concept generated by SACMA and Ingramatic works perfectly thanks to the fact that all components are manufactured by the SACMA Group factories on the latest CNC tools, giving complete control of the quality and providing many years of reliable production.

The unique manufacturing and inventory divisions assure spare parts availability if ever needed. Full service and spare parts are furnished from the SACMA technical centres around the world.

To support all its customers, SACMA Group has developed worldwide efficient service centres that are able to supply any spare part in a very short time to keep customer machines running and making parts. The technical centres are located in the United States, Brazil, China, Russia, Turkey, and eastern Europe. In Germany, there are no less than 12 technicians and engineers dedicated to SACMA and Ingramatic machines through SACMA’s Thiel Maschinen partner. This outstanding service is possible because the SACMA factories provide all the mechanical components on time and maintain a stock of spare parts. SACMA point out that all the spare parts for both brands are available within 24 hours.

Most recently, SACMA Group invested in a brand new facility for its technical centre in Wuxi, China. This building will allow SACMA Group to support customers better in a market that is demanding more and more SACMA and Ingramatic machines. SACMA Group can also train people and help in the maintenance process.

In addition, the SACMA Group network has been expanded with the hiring of new technicians in 2018 for the USA, Turkey, Poland and China. It is clear that the main objective for SACMA Group is to contribute to the success of its customers by exporting ‘Made in Italy’ quality machines.

“SACMA Group speaks the languages and is present in every time zone with a worldwide support network of service and technology centres, which the customers can contact at any time of the day. For sure, the SACMA ‘Made in Italy’ is the guarantee of continued productivity and success for all its customers.”
