Specialized Bottle Engineering: View-Stripe & Multi-Cavity Flow
Precision calibration for transparent oil level lines, hollow handle deflashing, and heavy structural backplates. Engineered for continuous industrial blow molding lines.
CONTINUOUS SHUTTLE TOOLINGContinuous Extrusion Multi-Cavity Lineup
Engineered for high-volume motor oil packaging plants running continuous parison shuttle machinery. Standardized center-to-center cavity distances match multi-die extrusion heads with zero parison swing.
- Die Matching: Precise center pitch alignment for 2-die, 3-die, and 4-die extrusion heads
- Synchronized Deflash: Dual-action pneumatic punch bars shear handle and tail flash simultaneously
- Thermal Uniformity: Balanced multi-channel cooling manifold guarantees identical cycle times across all cavities
VIEW-STRIPE TECHNOLOGYTransparent View-Stripe Parison Calibration
Engine oil and chemical jugs require a transparent vertical level stripe with embossed volume graduations (1L, 2L, 4L, 5L). Our cavity parting lines are microscopically adjusted to prevent stripe distortion.
- Parison Slit Matching: Co-extrusion die stripe channel perfectly aligns with mold cavity graduation ribs
- Wall Consistency: Balanced blow air dynamics prevent the translucent stripe from thinning or bowing
- Clean Embossing: Razor-sharp volume scale numbering (ml/Quart/Liters) molded directly into the bottle wall
PRE-HARDENED ALLOY BLOCKSHeavy-Duty Tooling Blocks & Gun-Drilled Circuits
Forged tool steel blocks are deep gun-drilled with high-turbulent spiral cooling channels. Beryllium copper inserts are positioned directly adjacent to handle seams where heat concentration is highest.
- Steel Hardness: Vacuum-treated P20 / 718H blocks (HRC 32–36) prevent parting line depression
- Pinch-Off Thermal Rate: C17200 Be-Cu cools parison flash 350% faster, eliminating seam drag marks
- High-Flow Manifold: Uniform water distribution maintains ±1.5°C cavity temperature across multi-parison sets
Pre-Hardened Tool Steels & Boring Center Accuracy
Precision multi-cavity EBM molds require deep gun-drilled cooling channels and rigid platen parallelism. We machine monolithic tool blocks using high-precision CNC horizontal boring centers.
HORIZONTAL BORING FACILITYCNC Horizontal Boring & Deep-Hole Drilling
Our heavy-duty horizontal boring centers drill continuous cross-circuit water channels through multi-cavity mold blocks, ensuring high-velocity water flow directly behind critical pinch-off zones.
- Boring Precision: Axis positional repeatability held within ±0.008mm
