A modular cover is provided to cover a molding tool, in which the cover comprises a plurality of plates configured to be coupled together to cover at least a portion of the surface of the molding tool, a fastening arrangement configured to fasten the plurality of plates to the molding tool, in which each of the plurality of plates has at least one coating of reflective material. A system and a method for manufacturing a structural element are also provided.

A device for blow molding a container from a preform. The device includes a mold base and a pedestal for supporting the mold base. An electric heating element is beneath the mold base for heating the mold base. An insulator is between the heating element and the pedestal.

This invention concerns a process for producing particle foam part in which foam particles are heated in a molding tool so that they weld to the particle foam part. Heat is supplied to the foam particles by means of electromagnetic RF radiation. The foam particles are made of polyurethane (PU), polylactate (PLA), polyethylene block amide (PEBA) or polyethylene terephthalate (PET).

A molding element having a molding surface forming a contact face and a groove forming rib portion forming the groove comprising two opposed rib side faces and a rib top face connecting two rib side faces. The groove forming rib portion provides at least one space opening to at least one of the rib side faces and/or to the rib top face. An insert is received in the space. The insert comprises a cavity for forming a closing device in the groove. The cavity has two opposed cavity faces and opens to at least two faces of the insert corresponding to the faces of the groove forming rib portion. The insert comprises at least one cutting means extending and/or projecting in a direction the groove forming rib portion extends for cutting a material filled in the cavity during demolding.

A calender for the treatment of web-like materials, including a fixed structure adapted to support two heated rollers shaped to be connected to the fixed structure, to a drive unit and to a heating system. The calender includes automatic elements for engaging and respectively for disengaging the rollers to and from the fixed structure, the drive unit and the heating system; the automatic elements are controlled by a programmable control unit and each of the rollers has an engaging surface shaped to be engaged by mechanical elements for moving the rollers which move the rollers between the calender and one or more waiting or parking stations while the rollers are at a temperature between 50° C. and 200° C.

The present invention is a system for producing an object from a material that contains a hardenable base material using rotational moulding, wherein the system is comprised of a robotic arm and a die that can be attached to the robotic arm. The die contains a die cavity defined by a die wall, wherein the die is configured for receiving the material in the die cavity. The current invention also involves a method for production of an object of a material containing a hardenable base material using rotational moulding.
