“…In contrast, other machining processes may vary in complexity and precision requirements depending on the specific application, with an emphasis on achieving desired dimensions and surface finishes rather than replicating complex shapes for mass production. As a result, mold making frequently necessitates manual or advanced finishing, comprising a significant portion of the overall operation time, approximately 17% [43,44].…”

The mold industry faces unprecedented challenges in the current global economic and social landscape, including increasing environmental concerns and the need for sustainable solutions. To address these challenges, the plastics tooling industry needs to face critical issues associated with the shortage of skilled labor and disruptions to global supply chains. This work reviews and analyzes the global workforce challenges and their relationship to sustainable economic and environmental growth. The characteristics and challenges of the mold-making and engineering industries are assessed and critically discussed. New technologies, such as data-driven automation in design and manufacturing, are discussed, considering their current and future impact on employment in the industry. Ultimately, the paper argues that the mold industry must address these workforce challenges to promote sustainable and continued growth. Indeed, workforce and technology development are the key drivers for the sustainable growth of the mold-making industry, as they support the timely and cost-effective manufacturing of numerous essential plastic products. The industry stakeholders should work on structural solutions to foster a more conducive environment to produce plastic molds.

The manufactured surface textures after machining operations may require the use of an abrasion operation in order to meet expected requirements. In this context, the simulation of the entire manufacturing process from machining to abrasion finishing could significantly improve the parameters involved in manufacturing. The simulation of the abrasion requires to handle a high number of interactions between the workpiece and abrasive grains as well as complex mechanical behavior during material removal. Considering numerical and physical constraints, a novel model for abrasion simulations based on an implicit surface representation has been developed which allows macroscopic simulations of surface topography resulting from abrasion. The surface is embedded in a scalar field, so that the removal action occurs throughout the modification of the volumetric data rather than an explicit interaction with the surface. In this article, the implicit model is enriched in order to be able to integrate the surface topography of the previous machining operation. Thus, the simulation of the resulting surface topography for an entire manufacturing process has been performed successfully. Several experiments have been carried out and analyzed in order to evaluate the proposed model. The comparison between simulations and experimental results validates the consistency of the model regarding real abrasion finishing processes.

“…Hence, the complete process is analyzed for balancing the milling as well as polishing times to lessen the total production time. The designed experiments were conducted on an aluminum mould for plastic bottles [26]. Mehdi Moayyedian et al made the new shape of the entire runner system in the plastic injection molding, and the aim of this geometry was to decrease the cycle time and scrap and also to eject the runner system from the moulds easily.…”

Design and manufacturing are the key steps in the sustainable manufacturing of any product to be produced. Within the perspective of injection molds production, increased competitiveness and repeated changes in the design require a complete optimized manufacturing process. Local and minor improvements in the milling process do not generally lead to an optimized manufacturing process. The goal of the new geometry and parametric analysis of the mould is to reduce the quality issues in mild steel grade 60. In this explicit research, the surface roughness (smoothness) of indigenously produced injection moulds in the local market in Pakistan is investigated. The CNC milling machine (five-axis) is used for the manufacturing of an injection mould, and the Taguchi method of the design of the experiment is applied for parameters optimization. Hence, the overall process is assisted in balancing the milling machine parameters to trim down the surface roughness issue in mild steel moulds and increase their sustainability. The spindle speed (rpm), the depth of cut (mm), and the feed rate (mm/rev) are considered as input variables for process optimization, and the experiments are performed on mild steel grade 60. It is deduced that the combination of a spindle speed of 800 rpm, feed rate of 10 mm/rev and depth of cut of 0.5 mm is the best case in case of minimum surface roughness, which leads to sustainable products. It is also deduced from ANOVA, that the spindle speed is a factor that affects the surface roughness of mild steel products, while the feed rate turns out to be insignificant.
