“…Figure 1 shows its basic principle: under specific temperature and pressure conditions, molten resin is injected into a mold with pre-positioned reinforcements such as fibers, and then cured and molded under appropriate temperature and pressure. The RTM process has the advantages of good molding results and applicability to a variety of shapes, but it also has some disadvantages, such as high cost and cumbersome process flow [8].…”

“…Compression molding is used to produce rubber parts by heating the mold and then placing a sheet of rubber in it, which is then compressed and cured. RTM (resin transfer molding) is used to produce composite parts by filling a mold with resin with an embedded fiber structure, which then cures and the part is removed from the mold [38,39]. These special molds are used for the mass production of a variety of products.…”

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 two primary categories of multiscale computational methods are typically upscaling and resolved scale methods. 25,26 The microscale and mesoscale responses of composites are homogenized in the upscaling methods, and their average mechanical response is utilized for macroscale simulations. This approach is computationally intensive as it requires an explicit representation of the micro-structure using the Representative Volume Element (RVE) concept.…”

The cure‐induced residual stresses have a significant influence on the deformation and mechanical properties of composites. Moreover, the cure‐induced residual stresses exhibit multi‐level and multiscale distributions due to the complexity of micro‐structure of composites and anisotropic characteristics. In this paper, a computationally efficient multiscale procedure is proposed to predict the microscopic residual stresses induced by cure temperature, cure shrinkage and macroscopic residual stresses, which is based to the linear viscoelastic theory combined with the micro‐mechanics method. The instantaneous microscopic residual stresses are expressed as a linear combination of the instantaneous temperature increment, degree of cure increment and macroscopic strain increment at all times of the cure process until to the current time. The proposed method is verified in comparison with the published results in literature and the microscale FEA at different length scales, respectively. The results show that the proposed method is about a thousand times faster than directly using FEA in the microscale RVE model once the influence coefficient matrices are determined. At length, the microscale stresses of all nodes of the entire macroscale model are examined by using the proposed method. It is found that the thermal‐chemical‐mechanical loads lead to serious microscopic stresses for the matrix and interphase constituents, especially for those due to the macroscopic residual stresses.Highlights Microscale residual stress is written as a linear combination of macroscale loads. Applying macroscale loads on microscale FEA model to obtain influence matrices. The presented model avoids repeatedly FEA microscopic to improve the efficiency. The online time required for the proposed model is much less than microscale FEA. The microscale stress increases the risk of matrix cracking and interface bonding.
