Frequently asked questions

The more we know about the job, the more accurate the quote. For a press: the part or product, the material and its thickness, the force you expect to need, table size, daylight and stroke, heating if any, and the output per shift. For a baler: the material, your daily volume, the floor space available and the bale weight you want.

Drawings, photos of the current setup or a sample part all help. If you are not sure about some values, say so, and our engineers will work them out with you.

It depends on the machine and how much of it is designed specially for you. A standard configuration is faster than a press with a special table size, heating or controls, and a custom machine needs design time before manufacture starts.

We confirm the delivery schedule in the quotation, once the configuration is agreed.

Yes. The quote request accepts drawings and CAD files (STEP, DWG, DXF, IGES), photos and videos. A short video of the current process, or of the machine you want to replace, often answers questions a drawing cannot.

Files you send are kept private and used only to prepare your quotation.

Yes. We have delivered a custom cotton baler to a client in Sudan, and we quote for buyers across the Middle East and Africa. Tell us the destination country when you request a quote.

Shipping, documents and installation abroad are agreed for each project.

Yes. Custom machines are a regular part of our work. We have reverse-engineered and improved an imported five-jaw scrap grapple, and designed a transportable cotton baler around a client's logistics.

Send us a description of the task, with photos or a video if possible. An engineer will tell you whether it is feasible and how we would approach it.

A vertical baler (PSG-RECV, 20–150 t, bales of 40–450 kg) suits smaller daily volumes and tight spaces: one operator loads it, presses, ties and ejects the bale. A fully automatic horizontal baler (PSG-RECH, 100–400 t, bales of 95–1250 kg) suits continuous, high volumes, with automatic bale ejection.

For scrap metal, the horizontal metal baler (PSG-RECM) is the right choice. If you are between two models, tell us your material and daily volume and we will recommend one.

On the fixed-platen version, the operator loads and unloads the die inside the press. On the moving (shuttle) version, the lower platen slides out of the press for loading and ejection, then returns for pressing.

The shuttle keeps the operator's hands away from the hot pressing area and makes loading easier. Both versions are available on the PSG-HPTF thermal forming press, from 80 to more than 600 t.

Required force depends on the process, the material and the size of the part. For moulding, it is mainly the pressure the material needs multiplied by the projected area of the part. For deep drawing, it depends on the strength of the material, the sheet thickness and the perimeter being drawn.

Add a margin above the calculated value so the press is not working at its limit on every cycle. Our engineers can check your calculation from a part drawing and the material data.

Yes. The PSG-HPTF thermal forming press stores more than 100 programs. Each program holds the settings for one product or mould, so a changeover means selecting a program rather than setting pressure, temperature and times by hand.

This shortens changeovers and keeps quality consistent between shifts and operators.

Bale weight depends on the baler and on the material: the same chamber produces a heavier bale from dense material than from light film or foam. As a guide, our vertical baler makes bales of 40 to 450 kg, the horizontal baler 95 to 1250 kg and the metal baler 400 to 1250 kg.

Tell us the bale weight your buyer accepts and the material, and we will size the machine to reach it.

Force equals pressure times piston area. To find the bore, use D = √(4F / πP), with D in mm, F in newtons and P in MPa (1 MPa = 10 bar).

Example: at 250 bar (25 MPa), a 200 mm bore gives about 785 kN, roughly 80 t. Choose a standard bore above the calculated value and leave a margin for friction and pressure losses. Our cylinder calculator and our engineers can check the result.

A tie-rod cylinder is held together by steel rods running outside the tube between the two end caps. It is compact, standardised and easy to service, and suits general machinery at moderate pressures. We make them to metric ISO classes of 160–200 bar and to NFPA ratings of 2500–3000 psi.

A mill-type cylinder has heavy end caps bolted to flanges on the tube, with no external tie rods. It is built for heavy, continuous duty and shock loads. We make them in 160, 180 and 250 bar classes.

Bore, rod diameter and stroke; working pressure; mounting style at both ends; port type, size and position; the hydraulic fluid and operating temperature; and the speed and load the cylinder must handle.

If you are replacing an existing cylinder, its measurements, its nameplate or the cylinder itself is the fastest route to an exact match.

External leaks at the rod usually mean worn rod seals or a scored, corroded or bent rod. Drift, where the cylinder slowly retracts or extends under load, often means the piston seals are leaking internally, although a valve in the circuit can cause the same symptom.

Contaminated oil speeds up seal and rod wear. New seals alone will not last if the rod or tube surface is damaged, so we always inspect and measure these parts during a rebuild.

Open a service request on the website and choose “Machine stopped” as the impact, or call or message us on WhatsApp. Add photos, a short video and the serial number from the machine's nameplate if you can.

You receive a ticket number by email and a link to follow the request. Stopped machines are handled with the highest priority.

Yes. Our maintenance and cylinder repair work covers equipment from other makers, including imported machines. One of our projects started with repairing an imported scrap grapple before we built an improved replacement.

We assess each machine first. If spare parts are no longer available, we can often design and make them.

There is no single interval. It depends on operating hours, oil temperature, how clean the environment is and the condition of the filters. Hot, dusty plants running several shifts need shorter intervals than a clean workshop running one.

The reliable method is to check the oil regularly for colour, smell, water and particles, and to change filters when their indicator or pressure drop says so. Follow the machine's manual, and ask us to help set up a schedule for your conditions.

Pernoscal is an Egyptian engineering company in 10th of Ramadan City, Al-Sharqia. We design, manufacture and maintain industrial hydraulic systems: four-column presses, recycling balers, hydraulic cylinders and their components, and custom machines.

We also provide maintenance, engineering design, consulting, technical support, installation and cylinder repair.

A locally built machine is engineered for your actual application and site, not adapted from a catalogue model. You deal directly with the engineers who designed it, spare parts and service are close by, and you avoid much of the cost and currency exposure of importing a complete machine.

Our aim is simple: give factories in Egypt and the region a real alternative to imported equipment, with the quality they expect and a lower operating cost.
