The ejection system is the key functional structure to ensure smooth demoulding of low-pressure castings. Unreasonable ejection point layout, unbalanced ejection force, excessive ejection speed and inaccurate pin height will cause product ejection deformation, surface scratches, ejection marks and even product cracking. Optimized ejection design can completely solve demoulding quality problems and protect product appearance and precision.
Uniform multi-point ejection layout realizes balanced force demoulding. According to the product outline and stress distribution, multiple ejection points are symmetrically arranged to disperse demoulding force. It avoids local concentrated force leading to thin-wall deformation and structural cracking, ensuring the overall uniform stress of the casting during demoulding.
High-precision ejection pin assembly eliminates appearance defects. All ejection pins are precisely calibrated after installation, with height tolerance strictly controlled within ±0.01mm. The flat and consistent ejection surface completely eliminates concave and convex ejection marks on the casting surface, ensuring smooth product appearance.
Buffered variable-speed ejection protects product surface. The low-speed start and uniform acceleration ejection mode avoids rigid impact and friction between the casting and the cavity. This optimized speed control reduces product surface scratch and wear rate by 88%, realizing zero-damage demoulding.
Custom special-shaped ejection adapts to complex products. For curved surfaces, deep cavities and irregular structural castings, customized special-shaped ejection blocks and auxiliary ejection structures are adopted to solve demoulding difficulties of special parts, avoiding forced demoulding damage.
Standardized daily maintenance maintains long-term ejection performance. Regular lubrication, wear detection and flatness calibration of ejection pins and guide structures avoid jamming, unbalanced ejection and pin deviation, ensuring stable demoulding effect of batch products.
