We industrialize and bring your ideas to life
Our most notable service, one that clients have trusted over the years, is the design, engineering, and manufacturing of all types of plastic, aluminum, Zamak and blow molds in Zaragoza.
INJECTION MOLDS
ALUMINUM
Ideal for producing high-strength, dimensionally precise parts for sectors such as automotive, electronics, weapons, and construction.
ZAMAK
Perfect for parts with fine details and high-quality surface finishes, used in sectors such as cosmetics, electronics, hardware, white goods, and decoration.
PLASTIC
Versatile and economical, they are suitable for a wide variety of applications in sectors such as automotive, packaging, toys, construction, and sporting goods.
How do injection molds work?
The two halves of the mold are closed and firmly clamped together to ensure a sealed cavity.
The injected plastic cools inside the mold, taking the shape of the cavity. This cooling can be done by water or air.
The molten material, usually in the form of pellets, is introduced at high pressure into the mold cavity through a nozzle.
Once solidified, the part is ejected from the mold by a pusher system, ready for use.
BLOW MOLDS
Ideal for the manufacture of bottles, containers, and other hollow plastic containers used in sectors such as food, beverages, and cosmetics.
Advantages of this type of mold:
High production: They allow large quantities of parts to be manufactured in a short period of time.
Versatility: They can be used with a wide variety of plastic materials.
High-quality surface finish: The parts can have a smooth, glossy surface finish.
Possibility of incorporating details: Complex details, such as logos or branding, can be incorporated into the parts.
Low cost per unit: The production cost per unit is relatively low, especially in high volumes.
How do blow molds work?
The plastic is transformed into a molten material or a preform (tube or parison).
The injected plastic cools inside the mold, taking the shape of the cavity. This cooling can be done by water or air.
The two halves of the mold are closed and firmly secured.
Once solidified, the casting is held in place by "tweezers" that keep it in position when the two parts of the mold are opened.
The molten material or preform is introduced into the mold. High-pressure air is then injected, forcing the material against the mold walls and forcing it into the shape of the cavity.
SAND MOLDS
Used for the production of unique or low-volume parts in sectors such as artistic casting, the valve industry, the irrigation industry, and the faucet industry.
Advantages of this type of mold:
Low cost: Sand molds are relatively inexpensive to manufacture, especially for single.
Ability to manufacture complex parts: Sand molds can be adapted to complex geometries that would be difficult or expensive to manufacture using other methods.
Repair and reuse: Sand molds can be repaired and reused multiple times.
How do sand molds work?
The sand is mixed with binders and other additives to give it the proper consistency and properties.
The molten metal is poured into the pre-mold we have generated through the sprues.
The sand mixture is compacted around a model or pattern that defines the shape of the pre-mold.
The metal cools and solidifies inside the mold, taking the shape of the cavity.
Sprues and risers are added to the mold to allow the molten metal to enter and gases to escape, respectively.
Once the metal has solidified, the mold is broken to remove the casting.
