Facing rising labor costs and recruitment difficulties, automation upgrading has become an inevitable choice for injection molding enterprises to reduce costs and increase efficiency. With numerous brands and models on the market, how do you select a robot that fits production needs and is cost-effective? When selecting, first clarify your own production conditions and technical specifications to ensure seamless integration with existing production lines:

• X-axis (Extraction Stroke): Related to product thickness, responsible for pulling the product out of the mold.

• Y-axis (Traverse Stroke): Responsible for traversing from the inside of the injection molding machine to the outside for placement after picking.

• Z-axis (Vertical Stroke): Determined by the required descent height and maximum product thickness, ensuring clearance over the machine body and placement at a reasonable height.

• Dual-Arm Robot: Suitable for enterprises with many three-plate mold products, mainly engaged in contract manufacturing.

• Single-Arm Robot: Suitable for enterprises using hot runner molds or two-plate molds with long-term production of their own stable products.

• Single-Stage Arm: Suitable for injection molding machines under 250T with sufficient overhead crane height.

• Double-Stage Arm: Suitable for enterprises with injection molding machines above 300T.

• Custom Double-Stage Arm: A must for workshops with low overhead cranes or height restrictions (dimensions can be specially customized).

• Cantilever Robot: Suitable for small machines under 150T, only gripping runners with products automatically dropping, simple movements.

• Traverse Robot: Suitable for machines above 50T, ensuring scratch-free appearance, supporting multi-action complex and orderly arrangement and packing.

• Single-Axis / Dual-Axis Servo: Traverse or main arm uses AC servo motor, supplemented by cylinder drive, high cost-performance.

• 3-Axis Full Electric Servo: High speed and high precision, capable of completing standard automation such as insertion, stacking, and cyclic placement.

• 5-Axis Full Electric Servo: Equipped with "quick pick, gentle place" function, perfectly suited for complex applications such as in-mold labeling (IML), inserts, and gate cutting.

Calculation Formula:Maximum Load = EOAT Net Weight + Product Net Weight

EOAT net weight is determined by product characteristics and process requirements. The sum of both must be controlled within the robot's effective rated load capacity to ensure long-term stable operation.
