XZ-988 Automatic Rotary Shoe Injection Molding Machine

Model: XZ-988/16-20-24-AS(C)

Manufactured by Ruian Xingzhong Industrial Co., Ltd., the XZ-988 AS(C) is a rotary direct injection shoe machine for PVC/TPR soles molded directly onto uppers. Applications include canvas shoes and casual footwear, subject to matching the upper, last, mould and material formulation.

AS(C) provides automatic mould opening and closing, while S(C) uses operator-controlled mould movements. Material preparation, upper loading and positioning, footwear removal and inspection remain operator tasks on AS(C).

  • PVC & TPR Processing

    Designed for PVC and TPR footwear applications, with foamed or non-foamed processing reviewed against the chosen formulation and mould. Confirm the material, required sole properties and footwear design before selecting a production setup.

    Explore PVC material options
  • Mold Cooling System

    Chiller-connected aluminum cooling plates help lower mould temperature, improve PVC sole shape retention and reduce cooling-related bulges. Shorter cooling time can support higher output. Xingzhong reports an average output increase of approximately 20% in practical applications, depending on sole thickness, size and production conditions.

  • Simplified Daily Operation

    Organize daily work around material preparation, upper loading and positioning, product removal and inspection. Operator allocation and training depend on the footwear and production layout; review these tasks alongside the machine-controlled stages.

    Follow the production workflow
  • Rotary Production Capacity

    Published reference output — 20 station: 250-300 pairs/hour; 24 station: 250-300 pairs/hour. Actual output depends on material formulation, footwear design, moulds, cooling requirements and operator coordination. Reference output is not a guaranteed production rate.

How the XZ-988 AS(C) Production Process Works

A production overview for direct-injection footwear using the AS(C) configuration with automatic mould opening and closing. Follow the equipment operating procedure for the detailed sequence and operator tasks.

  1. Material Preparation

    Prepare the approved PVC or TPR formulation and set the process parameters for the intended footwear. Confirm any material preparation requirements with the supplier.

    Explore PVC material options
  2. Upper Loading & Positioning

    The operator loads the upper onto the last and checks its position and fit before moulding. The upper, last and mould must match the intended shoe design.

  3. Automatic Mould Closing & Indexing

    After the operator has loaded and positioned the upper, the machine closes the mould automatically and indexes the rotary station for injection. Follow the AS(C) operating procedure for the detailed sequence and operator checks.

    Review the machine configuration
  4. Injection & Sole Formation

    The prepared material is plasticized and injected into the mould to form the sole against the upper. Material compatibility and process settings must be checked for the intended bond and shape.

    Compare technical specifications
  5. Cooling During Rotation

    Allow the moulded sole to cool as the rotary production sequence continues. Cooling requirements depend on the material, sole geometry and mould setup.

    Compare technical specifications
  6. Automatic Mould Opening, Removal & Inspection

    Following the required cooling stage, the mould opens automatically. The operator removes the footwear and checks appearance, sole formation and the upper-to-sole bond before downstream finishing.

Frequently Asked Questions

  • What materials can the XZ-988 process?

    The machine is intended for PVC and TPR footwear production. Foamed and non-foamed applications require a suitable formulation, mould and process setup. Other materials need a separate compatibility review; the linked material page covers PVC options.

    Explore PVC material options
  • What footwear can this machine produce?

    Listed applications include PVC and TPR shoe soles, Slippers and sandals, Direct injection footwear, Customized shoe production lines. For direct-injection footwear, confirm the upper, last, mould and material combination. Share a sample or drawing so we can assess the intended construction and production layout.

    Review DIP shoe moulds
  • What is the production capacity?

    Published reference output — 20 station: 250-300 pairs/hour; 24 station: 250-300 pairs/hour. Actual output depends on material formulation, footwear design, moulds, cooling requirements and operator coordination. Reference output is not a guaranteed production rate. Share your shoe style and target output for a production review.

    Compare technical specifications
  • How do I choose between 20 and 24 stations?

    Compare the available configurations against cooling requirements, product mix, mould investment and factory space. More stations do not automatically mean a proportional increase in hourly output. Use the configuration-specific dimensions and reference output in the table when planning the layout. The 20- and 24-station configurations currently share the same published reference output range.

    Compare technical specifications
  • Which operations are automatic on the AS(C) model?

    The AS(C) model provides computer-controlled operation with automatic mould opening and closing. Upper loading and positioning, footwear removal and inspection remain operator tasks. Compare these functions with the S(C) configuration when selecting a machine; automatic mould handling does not by itself imply a higher hourly output.

    Compare the XZ-988 S(C) model
  • How many operators are required?

    Staffing is assessed for your shoe style, loading and unloading tasks, shift plan and production layout. Clarify whether material handling, trimming and quality inspection are included in the headcount. Operator training and safe operating procedures are required; no fixed staffing or training-time claim is made here.

    Review the operator tasks
  • What utilities and installation space are required?

    Check the selected configuration's power and machine dimensions in the specifications. Installed power is not a measurement of actual electricity consumption. Allow additional space for access, material handling and maintenance; confirm the electrical supply and cooling or other utility connections in the project proposal.

    Compare technical specifications
  • Can my existing moulds be used?

    Existing moulds need a compatibility review covering dimensions, mounting interfaces, lasts and injection position. Matching external dimensions alone is insufficient. Send mould drawings or photographs and details of the intended footwear before assuming compatibility.

    Review DIP shoe moulds
  • What should I provide to request a quotation?

    Send shoe samples or photographs, material details, the size range, target output, existing mould information, available electrical supply and delivery destination. These details help define the machine, mould and material proposal.
