Warpage Prediction of RHCM Crystalline Parts Based on Multi-Layers
, 2021 Warpage is a typical defect for injection-molded parts, especially for crystalline parts molded by rapid heat cycle molding (RHCM). In this paper, a prediction method is proposed for predicting the warpage of crystalline parts molded by the RHCM process.

Spring-in and Warpage — Progress in Simulating Manufacturing Aspects
Mechanics of Composite Materials, 2013 After demolding, plane structures made of fibrous polymer-matrix composites often show a warpage and, owing to spring-in angles, do not reach the designed shape. Considerable effort has been put into the development of methods for simulating the distortions in order to avoid them by countermeasures. Besides the empirical trial-and-error-based procedure,

Simulation of Shrinkage and Warpage of Rotationally Moulded Polymer Parts
, 2020 The rotomoulding industry is impeded by long manufacturing cycle times, due to insufficient time required for the materials to achieve a stable state on cooling. Thermal residual stresses are induced in rotomoulded parts due to uncontrolled heat transfer,

Warpage prediction of integrated circuits packages
, 1997 Warpage is formed as a result of the thermal mismatch between the IC package components. The warpage problem becomes a critical issue particularly in large and thin packages such as thin quad flat package (TQFP).
