GMA Machinery Enterprise Co., Ltd products

Upper die lip adjustment by one push/one pull structure. Uniform sheet thickness of allowance within ±3%.

Special coat-hanger type manifold design. Reduce heat sensitive polymer cracking in the extrusion process. Suitable for foam sheets of different polymers and thicknesses (3-35 mm thick).Adjustable upper die lips, replaceable lower lip, vertical flow restrict bar.

Quality manifold design.Uniform and consistent temperature across different regions, uniform and stable output. Quality die lip, manifold flatness.Meet demanding requirements for roughness, thermal deformation and heat uniformity.

Simple manifold structure, few retention points. Customized manifold design, 2 or 4 inlets, for different Extrusion Die inlet as required by the customer. Recision internal manifold design along with special surface treatment. Corrosion, heat and wear resistant design. Manifold design varies with rheology property of polymer material to adapt to features and strength of rheology of melted polymers. Applicable with multi-layer composite production requirements of different materials.

Direct changing thickness of individual layers during production Easy operation, production costs reduction. Multi-layer space design according to product requirements. Interchangeable selector as required by customer to adapt to different products and changing layers required by the customer. Precision internal manifold design along with special surface treatment. Corrosion, heat, and wear resistant design. Adaptive to features and strength of rheology of melted polymers. Applicable with multi-layer composite production requirements of different materials.

Rapid Variable Geometry Feed Block. Easily and Rapidly change product structure during production, ONLY take 1-2 hours for changing. Applied on single to three layers product without selector, such as BAB to AB or to BA or to A. Five-area design of flow distribution bar, controlling flow perfectly, ensure the distribution of top or bottom layer is even, save cost. Precision internal manifold design along with special surface treatm
