To facilitate functional hydrogel part production using the indirect wax mould method, it is necessary to understand the relationships between materials, process and mould removal. This research investigated the thermophysical properties, wettability and surface roughness of wax template moulds in the production of cellulose hydrogel objects. Cellulose gel was thermally formed and shaped in three different wax moulds—high melting point paraffin, sacrificial investment casting wax and Solidscape® wax—by physical cross-linking of polymer networks of cellulose solution in NaOH/urea aqueous solven

Apart from mould and core remnants attached to metal objects from the Chalcolithic Southern Levant (ca. 4500–3800 BCE), production remains of early lost wax casting are seemingly invisible in the archaeological record. An experiment using reproduced casting moulds was performed to simulate the Chalcolithic processes to investigate whether the moulds might have deteriorated to an unrecognisable state after the casting process. Results from previous studies on mould remains attached to metal objects were complemented with ethnographical accounts for the experimental set-up. The moulds were

Apart from many lost wax cast metal fragments, crucible fragments and several heated sediment nodules were found at the Chalcolithic site Fazael 2 (central Jordan Valley). Petrographic investigations on the heated sediment nodules revealed many features characteristic of the Chalcolithic Southern Levantine lost wax casting moulds. Heating temperatures were assessed using infrared spectroscopy, showing that casting did not vitrify the clay fraction in the moulds. Consequently, Fazael is the first identified Chalcolithic Southern Levant production site for lost wax cast metal items. These findin

Abstract One of the major causes of magnesium corrosion is the presence of iron in commercial alloys as an impurity. A possible way of reducing the corrosion rate down to acceptable levels is to alloy the material with manganese. The corrosion rate of a Mg-9% Al-1% Zn alloy, containing varying amounts of Mn and Fe, is correlated with the Fe/Mn ratio in the alloy and in the aluminum-base intermetallics. The ratio is shown to be the basic parameter determining the corrosion rate for a given thermo-mechanical history.

Abstract Traditionally investment casting of biomedical implants has utilized the lost wax process, this paper is an investigation into the possibilities of casting small lots of custom specific medical implants directly and indirectly from various rapid prototyping &amp; tooling techniques. Small batch quantities for quick turn arounds cost and lead times are the main contributing factors for the purpose of this investigation. To directly produce parts means that a RP model will be used in the place of the wax pattern in the investment casting process. To indirectly produce parts means that a

Manufacturing companies need to improve their production technology with improved dimensional accuracy at lower cost in order to manufacture sheet metal based products. Scrap shedding is an issue that should be examined at the cutting and sheet metal forming operations. In order to extend the life cycle of the cutting moulds, scrap shedding should be identified. When scrap shedding has not been taken into consideration, scraps have accumulated in the moulds reducing the production quality and causing deformation of the mould, increasing the production cost by obligating to perform extra transa

Injection molding of thermoplastic is a complex process essentially because of the physical properties of the polymers, the processing conditions and the mold geometry. One key issue is to find the optimal location of the injection point(s) so that to minimize the final pressure required to fill the mould. This is usually achieved by using commercial computer codes, which are time consuming. Our approach, which is not classical, consists in introducing several “geometrical tools” of image analysis such as optimal centering and skeleton transformation, to characterize the shape properties of th

Abstract. The manufacturing of single crystal nickel-based superalloys components, such as turbine blades, using the lost-wax casting method is a complex process that can generate various defects. Among them, the recrystallisation defect, which is the focus of this study, occurs during solidification. This defect is characterised by the formation of highly misoriented grains, leading to a significant degradation of mechanical properties. The formation of these grains is partly attributed to the introduction of plastic strain in the alloy during cooling, caused by the difference in thermal expa

An archaeological excavation of the protected burial mound Store Vejlhøj in northwestern Denmark was carried out in October-November 2021. The excavation formed part of the ERC-funded research project called ANTHEA, focusing on the deep history of anthropogenic heathlands. It was conducted by Aarhus University in collaboration with Holstebro Museum and Moesgaard Museum. The aim was to test a new method of sampling pollen data from different construction stages in a burial mound and comparing them with pollen data from nearby lake sediments with a view to improving our understanding of prehisto

Finland's building regulations and guidelines rely on ventilation to ensure the hygrothermal performance of structures. For wooden roofs, height of ventilation cavity and area of ventilation openings have been determined depending on roof slope and roof area in guideline. This causes difficulties in practical implementation in low-slope roofs with large span, because the guideline leads to large ventilation openings that can be challenging to be implemented. In practice, roof element suppliers have produced roofs with slightly smaller height of ventilation cavities and areas of ventilation ope

In Denmark, many old buildings are constructed with massive masonry basement walls. Originally, these basements were used for storage or as boiler room. Hence moisture in the basement walls was not considered a problem, and moisture protection of basement constructions was not considered necessary. However, leaving older buildings basement walls exposed to moisture from the surrounding soil, results in a high risk for damage and mould growth on the interior surface of the exterior basement walls. Today, many of these basements are used for daily purposes. Accordingly, moisture problems in the

Bio-based as well as biodegradable polymers are increasingly finding their way into applications such as food packaging. Here, certain biopolymers with a high degree of crystallinity may be of interest due to their superior barrier properties. Conversely, forming processes including high deformations often require an almost amorphous material state to avoid the brittle behavior associated with crystal structures. For some of those biopolymers, the narrow window in which they can be processed has delayed their potential use for packaging applications. In rigid packaging, two-step processes are

The purpose of this research is to build an understanding of the current state of the practice for field-curing methods. Specifically, the research team conducted a literature review and questionnaire survey to identify the selection criteria and details of field-curing methods.
