Key takeaways:
Lamination is the final step where all module layers are mechanically consolidated
Autowell’s KM251/252 series offers multiple configurations, including single- and double-stack designs with 2- or 3-stage lamination processes
The laminators support a wide range of module types and operate with silicone membranes at temperatures up to 180°C
The next step after bussing, which involves connecting of strings, is lamination. In this step, a rear cover, comprising an encapsulant layer and either a backsheet or a rear glass, similar to the front stack, is added. With this, all the layers of the module are in place but still require mechanical and environmental reinforcement, which is achieved by lamination.
Lamination usually consists of 3 stages: pre-heating, pressing and curing, and cooling. These steps occur in a single-, double-, or triple-chamber laminator, depending on the make and throughput of the laminator. The conventional laminators feature at least 2 chambers for the lamination process. After lamination, the modules proceed to subsequent processes such as junction box installation and framing.
The TaiyangNews Market Survey on Solar Module Production Equipment 2026 features a total of 6 laminator models from 4 companies: Autowell, Jinchen, Mondragon, and Robert Bürkle.
Autowell’s product catalog also features a laminator model, KM251/252, with fewer details compared to those described for other laminators in this section. This model comes in 3 variants: 2 based on a 2-stage design, but in single and dual-stack configurations, and the third is a larger 3-stage double-stack configuration. The ‘stage’ here indicates the process steps; for example, a 3-stage includes pre-heat, hot press, and cooling cycles. Except for this configuration difference, the majority of the available specifications are identical for all the models. All the variants have a maximum effective laminating area of 2,700 × 11,500 mm. The laminators are said to be compatible with various module types, including all crystalline silicon modules, perovskite, Cd-Te thin-film, BIPV, and flexible modules. These products use a silicone membrane during lamination. These laminators are supported by either oil or electric heating, reaching a maximum operational temperature of 180°C. The tool also features lifting pins.
