模芯组件| ASB-12M 15ml 1×6腔顶芯固定板

产品概述

这 Dedicated Eject Core Fixing Plate (Part No. 83) is a single-component structural spare part engineered specifically for the Japanese ASB-12M 15ml 1×6 cavity tooling configuration. While often overlooked as just a mounting plate, this 275×75×40 mm precision-ground steel block is actually the kinematic foundation of the entire ejection system. Its planarity tolerance determines whether your ejector pins travel true, and its structural rigidity determines whether the pins maintain perpendicularity under the cyclical 5,000+ Newton loads typical of ASB-12M high-speed ejection strokes.

For Korean pharmaceutical contract manufacturers and cosmetic sample filling operations running ASB-12M equipment beyond the 3-year mark, fatigue in this specific fixing plate is one of the earliest root causes of production defects. Visible symptoms include unilateral wall thickness variation on the 15ml bottles, base gate stretching, unexpected ejection pressure spikes on the machine's servo or hydraulic monitor, and visible flash appearing around the preform neck ring area. All of these trace back to a warped or out-of-tolerance fixing plate allowing the ejector core assembly to shift microscopically during each production cycle.

Our replacement part is manufactured strictly to the original P2504-A068 series blueprint on 5-axis DMG Mori CNC machining centers, with all critical mating surfaces undergoing secondary precision surface grinding to achieve flatness and parallelism tolerance under 0.02 mm and surface roughness of Ra 0.8. The result is a drop-in replacement that restores your ASB-12M ejection station to factory-fresh kinematic precision without requiring any machine platen modifications, shimming, or bench-fitting by your maintenance team.

Korean buyers typically evaluate this component against three alternatives: the Nissei ASB OEM spare (8-12 week lead time, approximately 2.2× the Ever-Power price), generic Chinese aftermarket parts (dimensional tolerance often ±0.1 mm, inadequate for ASB-12M kinematic requirements), and in-house grinding of existing worn plates (rarely restores planarity sufficiently for long-term stability). For facilities running pharmaceutical or premium cosmetic production where reject rate directly affects regulatory compliance, the Ever-Power drop-in replacement is the only option that delivers Japanese-equivalent precision with 2-week delivery to Korean destinations.

Product Core Specifications Quick Reference

For production managers and maintenance engineers requiring immediate verification of replacement part compatibility with existing ASB-12M installations, the critical engineering parameters below reflect the current P2504-A068 Part No. 83 specification. All data points trace directly to our CMM inspection reports generated on every individual plate before shipment.

Component Function & Kinematic Importance within the ASB-12M

In the single-stage injection stretch blow molding ecosystem, the ejection station represents the critical final step of the production cycle where finished 15ml bottles must be stripped cleanly from the core rods and transferred to the downstream conveyor. The Eject Core Fixing Plate (Part No. 83) serves as the foundational rigid backbone for the entire ejection core assembly. Operating a 1×6 cavity layout for 15ml containers inherently concentrates significant mechanical stress into a compact 275×75×40 mm geometric footprint, making planar rigidity the single most important mechanical property.

As the foundational fixing plate, this component guarantees precise synchronized movement of the ejection cores across all six cavities simultaneously. It directly determines the dimensional stability and smooth demolding of finished 15ml bottles. If this plate experiences even microscopic deflection (flexing) under the cyclical 5,000+ Newton ejection load, the resultant angular misalignment transfers immediately to the ejector pins and core rods. This micro-misalignment causes kinematic binding, a destructive condition where metal galls against metal, leading to premature wear of ejector sleeves, core shifting, and ultimately severe damage to the primary mould components that cost $40,000 to $80,000 USD to replace.

Solving the Primary Operational Pain Points

Replacing a fatigued, warped, or out-of-tolerance original fixing plate with our precision-engineered counterpart eradicates prevalent ejection anomalies that plague Korean ASB-12M installations older than 3 to 5 years. The specific symptoms our replacement resolves include:

• Asynchronous ejection where bottles hang up on one side of the 1×6 cavity array, causing line stops and manual intervention
• Frictional shudder during the ejection stroke visible on the machine's servo pressure monitor as pressure spikes
• 压力美白 on the preform/bottle base caused by localized pin pressure due to misalignment
• Neck ring damage from uneven ejection force distribution across the six cavities
• Premature ejector pin failure requiring unplanned maintenance and replacement

By restoring absolute planar alignment, the replacement plate safeguards the structural integrity of your primary injection mould stack and keeps the entire ASB-12M production cell running within specification. For Korean pharmaceutical facilities where a single production stoppage can invalidate a GMP batch and force disposal of thousands of bottles, this structural reliability has economic value far beyond the plate's own purchase price.

Metallurgical Superiority & Precision Machining Workflows

The selection of materials and the exactness of subtractive manufacturing processes dictate the lifespan of the Eject Core Fixing Plate. Unlike cosmetic surface components, this plate is a highly stressed structural member operating in an environment characterized by rapid thermal cycling from ambient to 85 Celsius and intense mechanical shock on every ejection stroke.

Material Science: High-Grade S45C Carbon Steel

We strictly utilize premium certified S45C medium carbon steel (equivalent to AISI 1045) for this specific component. S45C is engineered with carbon content ranging from 0.42 to 0.48 percent, providing an exceptional balance of tensile strength, high modulus of elasticity (rigidity), and excellent machinability for precision CNC work. Each steel block undergoes rigorous normalizing and tempering heat treatment to relieve internal residual stresses prior to final machining, ensuring the 275×75×40 mm block will not warp or distort when subjected to operational temperatures of the ASB-12M platen area during continuous production shifts.

The high structural rigidity of properly heat-treated S45C effectively dampens harmonic vibrations generated during the rapid ejection stroke, protecting delicate 15ml cavity geometries from cumulative fatigue damage. Compared to alternative materials, S45C is the engineering-optimal choice for this specific role: P20 pre-hardened tool steel adds unnecessary cost (the plate does not contact plastic flow), generic low-carbon steels lack sufficient tensile strength, and aluminum alloys lack the Young's modulus required for vibration damping.

Advanced CNC Machining and Geometric Tolerancing

Fabrication is executed on 5-axis DMG Mori CNC machining centers to ensure all critical features are cut in a single setup, eliminating datum shifting errors that plague multi-setup manufacturing. We strictly adhere to original OEM blueprint tolerances documented in the P2504-A068 series. All primary mating surfaces undergo precision surface grinding on a Mitsubishi grinder to achieve flatness and parallelism tolerance under 0.02 mm and surface roughness of Ra 0.8.

The critical M8 threaded mounting holes and dowel pin alignment bores are subjected to rigid positional tolerancing, guaranteed within ±0.02 mm of true position. Furthermore, all non-functional sharp edges are meticulously processed with C1.5 to C2.0 chamfers to eliminate stress risers that could initiate crack propagation over the 5+ million cycle production lifespan, and to ensure safe snag-free installation by your maintenance technicians during emergency replacement scenarios.

The following table translates critical blueprint data into verifiable parameters for your engineering team to cross-reference against existing P2504-A068 series tooling before placing the procurement order.

Absolute Compatibility & System Interchangeability

100% Direct OEM Replacement Guarantee

This Eject Core Fixing Plate (Part No. 83) is manufactured in strict accordance with the original P2504-A068 series engineering drawings. We guarantee 100 percent dimensional, geometric, and functional compatibility with the ASB-12M injection mould assembly. It serves as a direct plug-and-play ASB mould replacement component, and absolutely no localized grinding, shimming, or machine platen modifications are required during installation. For Korean maintenance crews, this means the plate can be dropped in during a scheduled 4-hour maintenance window without any extended production disruption.

Applicable Tooling Series

This part is explicitly engineered for the 15ml bottle format operating within a 1×6 cavitation layout. The specific 275 mm length spans the exact pitch of the 6-cavity linear array, ensuring equalized ejection pressure distribution across all six stations simultaneously. This equalization is what prevents the core pin deflection on outer cavities that becomes increasingly problematic as the original Japanese plate accumulates fatigue damage over millions of production cycles.

Associated System Components

When replacing the Eject Core Fixing Plate, our engineering division strongly recommends simultaneously inspecting related mould train components. Specifically, evaluate the integrity of the stretch rod cover plates, ejector stripper plates, and primary cooling blocks (notably those utilizing ORRC PLAST materials for enhanced heat transfer). Ensuring the entire ejector sub-assembly remains within tolerance guarantees the most stable production environment and maximizes the service life of the new replacement plate.

Application Scenarios, High rPET Demands & Preventive Maintenance

When Is Replacement Mandatory?

Korean maintenance managers should schedule replacement of the Eject Core Fixing Plate when any of the following symptoms appear during normal production:

• Visual inspection reveals deep galling, scoring, or fretting wear on the mounting faces
• The 15ml bottles exhibit unilateral wall thickness variations or base gate stretching, indicating off-center preform ejection
• The machine's servo or hydraulic ejection load monitor shows unexpected pressure spikes, suggesting kinematic binding in the core assembly
• Visible flash appearing around the preform neck ring area due to inadequate closing alignment during the injection phase
• Laser planarity measurement across the mounting face exceeds the 0.05 mm specification threshold

The High rPET Challenge

As the Korean and East Asian packaging industry moves aggressively toward sustainability, utilizing ISBM moulds supporting high recycled PET (rPET) content ratios has become standard across beverage, cosmetic, and food applications. rPET blends often exhibit different shrinkage and stickiness profiles compared to virgin resin, requiring higher ejection forces to strip the preform from the core rod. This intensifies the mechanical load on the Eject Core Fixing Plate by 20 to 35 percent depending on recycled content percentage. Upgrading to our precise unyielding S45C plate ensures your tooling withstands the increased mechanical stresses of running 50 to 100 percent rPET without deflecting or jamming.

Expert Installation & Preventive Maintenance Protocol

To maximize the lifecycle of Part No. 83, Korean maintenance teams should adhere strictly to the following installation parameters:

1. Surface Preparation — Thoroughly clean the ASB-12M platen interface and fixing plate mating surfaces using residue-free industrial solvent. Even a 0.05 mm speck of carbonized resin or grit can cause the plate to seat out of parallel.
2. Pre-Lubrication — Apply a microscopic film of extreme-pressure (EP) copper anti-seize compound or high-temperature lithium grease to dowel pins and M8 threaded holes to prevent galling over the service life.
3. Torque Sequence — Insert all M8 fasteners loosely. Using a calibrated torque wrench, tighten bolts in a strict cross-diagonal (star) pattern in three incremental stages to reach the factory-specified final torque. This prevents localized stress concentrations and guarantees uniform planar seating.
4. Routine PM — Include this plate in your 500,000-cycle preventive maintenance checklist. Verify torque specifications remain tight and use a dial indicator to check for any loss of parallelism indicative of mechanical issues in the machine's tie bars.
