FIELD: process engineering.SUBSTANCE: set of invention relates to production of moulded articles with coatings with completely or partially structured surfaces, unit to this end and formed article thus made. Claimed process comprises injection of moulding mass at 220-330°C. Mid cavity is formed in the mould. Formed cavity is filled with reaction mix by fluid injection. This mould is sealed and heated at preset conditions and, then, is cooled down to withdraw moulded article. Besides, invention discloses the unit with injection mould to implement described process. Said method and unit allow the production of moulded articles with preset coating.EFFECT: high mechanical properties, namely, cracking stability and high rigidity.14 cl |
