Problems solved by technology

The problem also in this method is that the molds are expensive and the equipment used is only suitable for that particular method
A further problem is that using prior art compression methods, such as compression molding and injection molding, only smaller items can be manufactured economically, and then often only in large batches

Embodiment Construction

[0027]A hydraulic pressing unit for the manufacture of different products, for example from one material and various composite and laminated materials, by different compression methods such as compression molding, vacuum forming and injection molding products manufactured by the method. The solution according to the invention comprises a strong pressure-resistant frame 1 and also a pressure chamber 6 to be arranged inside it, in which the mold is surrounded by high pressure and temperature, and wherein the bottom chamber part 8 of the pressure chamber 6 can be App is replaced. This solution also includes the use of high temperatures, so that post-processing of the product to be manufactured with an autoclave is avoided. Using the solution according to the invention techniques known in particular from plastics molding technology and already used, for example, in injection molding moulds, are applied.

Abstract

The object of the invention is a method and a mold arrangement for the manufacture of objects by means of moulds. The solution according to the invention consists of a strong pressure-resistant frame (1) and also of a pressurized box (6) to be arranged in it, in which the mold can be surrounded by high pressure and temperature. By using high temperatures, post-processing using an autoclave is avoided. A bottom part suitable for the manufacturing technology can be arranged as the bottom part of the pressurized box (6), in which case using the solution according to the invention, known from plastic molding technology and used for example for vacuum forming molds and injection moulding. In-mold techniques are applied to items and molds that will be manufactured using compression molding techniques.

Description

technical field [0001] The invention relates to a method for manufacturing an article with the aid of a mould, and a mold arrangement for manufacturing an article with the aid of a mould. [0002] Due to its versatility of use, the method and mold arrangement according to the invention, ie the solution according to the invention, can be applied to manufacture many different products in moulds. In manufacturing, various existing technologies and their advantageous aspects are combined so that the product to be manufactured can be small or large in size and from different raw materials such as manure, straw, sawdust or wood chips, paper, plastic , rubber, metal, etc. Furthermore, the solution according to the invention can be applied to the rapid manufacture of very different composite materials. Background technique [0003] Articles consisting of different materials, having different shapes or dimensions and otherwise differing are produced in many different ways with the ...
