Product selection
What is the difference between accumulator-head and continuous extrusion blow molding machines, and when is each used?
The main difference is how the parison is formed: an accumulator-head machine accumulates melt and then extrudes the parison; a continuous extrusion machine forms the parison continuously. At Waley, WLA is the accumulator-head series, WLU is the continuous extrusion series, WLP is the multi-layer co-extrusion series, and WLC is the Customized series.
Selection should review the article drawing, target volume, materials, layer structure, capacity targets, and site conditions together. Do not decide from capacity or series name alone. You can share these materials first and then discuss options with the technical team.
What is the largest drum size Waley machinery can produce?
The confirmed article-volume range for standard WLA machines is 30–200 L, excluding customized projects. The maximum article volume for WLA-200L is 200 L. Article volume is not accumulator volume, and it does not by itself state output, accumulator size, or other machine parameters.
Capacity for other models or projects should be confirmed in a specific technical proposal. This page does not publish a full-line maximum capacity or customized-capacity commitment.
What is the difference between WLA and WLC?
WLA is the accumulator-head series. WLC is the Customized series. Standard WLA article volume is 30–200 L, excluding customized projects. WLC capacity is confirmed per machine model; this page does not list specific WLC models or a unified capacity range.
Series names do not replace configuration checks. Please describe the article, materials, and process requirements so drive, controls, molds, and acceptance conditions can be confirmed. Do not infer accuracy, energy savings, or output from the series name alone.
How many co-extrusion layers can Waley machines produce?
The multi-layer co-extrusion series is named WLP. Layer count is confirmed per machine model and configuration. Capacity is confirmed per machine model. This page does not publish a unified layer-count range or a specific WLP model list.
When inquiring, please describe the target article, layer materials, and the packaging performance you need, then discuss layer structure and machine configuration. An application name alone is not a materials or industry-compliance guarantee.
What are the differences among HDPE, LDPE, PP, PVC, and similar materials?
These names refer to material families. The name alone is not enough to decide whether a grade can be used for a given article or machine. Check the specific grade, supplier data, article use, and requirements for appearance, sealing, media contact, and testing.
Please provide the material grade or datasheet, article drawings, and use conditions so the technical team can confirm suitability and process options. This page does not treat legacy material comparison tables or temperature charts as general selection guidance, and it does not infer food or pharmaceutical compliance from a material name alone.
Pricing & commercial
How much does a blow molding machine cost?
A quotation requires confirmation of the article, materials, target output, layer structure, machine configuration, and project scope. You can start by sending article photos or drawings and noting mold, auxiliary equipment, and process-link needs.
This page does not list placeholder prices or a unified price range. Equipment scope, deliverables, commercial terms, and the final amount are governed by the mutually confirmed quotation and contract.
What is the equipment lead time?
Lead time is confirmed per project, machine configuration, and contract. A unified public range is not published. During requirement discussions, please share the project location, preferred schedule, and configuration needs so both sides can confirm delivery milestones and conditions.
What are the payment terms? Is installment payment available?
Payment ratios and milestones are confirmed per project and contract. Unified public standards are not published. Whether installments are available and how payments are arranged must be confirmed with sales for the specific project and written into the agreement. This page does not promise installment or financing services.
Process parameters
What processing temperatures should be used for PE and PP?
Processing temperature cannot be set from the PE or PP family name alone. Confirm it against the specific material grade, machine, die head, article, and process plan. Provide the material datasheet and the matching equipment documents; use the confirmed process file and the machine operating manual.
This page does not publish a general temperature table, tuning steps, or heat-up wait times. Start-up and heat-up waits follow the corresponding machine operating manual and after-sales guidance.
What wall-thickness accuracy can be achieved?
Wall-thickness accuracy is confirmed per machine model and test conditions. A unified public figure is not published. When discussing accuracy, specify the article, materials, measurement locations, methods, and acceptance conditions.
The number of wall-thickness control points is confirmed per machine model and control configuration. Control-point count is not the same as article accuracy. This page does not publish a unified point count, control-brand package, or accuracy comparison ratio.
What output can the machine achieve?
Output should be confirmed for the specific machine model, article, and test conditions. Even for 200 L articles, this page does not publish a unified reference output. Cycle time, cavity count, and accepted yield cannot be inferred from volume or series name alone.
Please provide drawings, materials, target output, shift pattern, and site constraints so test and acceptance conditions can be stated in a specific technical proposal.
How should blow-up ratio be set, and what control advice applies?
Blow-up ratio design must be checked against article shape, mold, parison, materials, and machine conditions. Experience ranges from other articles should not be copied directly. Bring article drawings plus mold and material data to discuss a specific plan.
This page does not publish a unified recommended ratio, die-gap setting, or adjustment procedure. Actual settings follow the process file, operating manual, and technical guidance for the corresponding machine model.
What raw-material utilization rate can be expected?
Material utilization first requires a clear measurement scope—for example how input material, good articles, flash, and regrind are counted—then checking against the specific article and operating conditions. This page does not publish a unified utilization rate, industry benchmark, or regrind ratio.
Please describe materials, article requirements, and measurement goals before confirming a workable approach. Material reuse alone does not prove article performance or end-use compliance. Scrap rate is confirmed separately per machine model, article, operating conditions, and counting rules.
Are there special process points for IBC / tote production?
IBC-related projects need separate checks of container requirements, materials, molds, equipment, and acceptance documents. This page does not publish IBC-specific parameter tables or equipment-capability commitments, and it does not infer from legacy site content that a given series fits that project.
The confirmed article-volume range for standard WLA machines is 30–200 L, excluding customized projects. That range is not a statement of suitability for an IBC project. Please share project materials for item-by-item technical confirmation.
Machine operation
How should start-up and commissioning be done?
Start-up and commissioning must follow the operating manual for the specific machine and version, the confirmed process file, and on-site training requirements. First confirm the machine model, serial number, control configuration, and manual version. Contact after-sales if documents are incomplete or operating meaning is unclear.
This page does not publish a general start-up sequence, temperatures, pressures, or heat-up wait times. A web answer cannot replace the operating procedure for a specific machine.
Is the equipment difficult to operate?
Operating requirements depend on the machine model, control configuration, production task, and operator training. This page does not promise that no training is needed or that operators will be proficient immediately. When inquiring, describe operator experience and the actual task so the HMI, manuals, and training scope can be checked.
Installation and training are confirmed by project location, contract, and service terms. This page does not infer training fees, on-site scope, or service duration.
How is the wall-thickness program set, and how are control points allocated?
Wall-thickness programs should be checked together with the article, materials, mold, and control configuration. Control-point count is confirmed per machine model and control configuration. Point allocation, recipe units, and setup methods follow the corresponding operating manual and the confirmed process file.
Provide the machine serial number, control configuration, and article requirements to the technical team. This page does not publish a unified point map, thickness curve, or touchscreen operating steps.
How should material purging and color change be done?
Purging and color-change methods must be confirmed against the machine, die head, resin, and colorant data. Cleaning materials, temperatures, sequence, and operating conditions follow the corresponding machine operating manual and after-sales guidance.
Describe the current material, the intended replacement material, and machine information before confirming a plan. This page does not publish general heat-up increments, cleaning cycles, or material-substitution instructions.
Troubleshooting
Who should be contacted for machine repair?
Contact Waley by phone at +86 138-2969-2592 or email waleymachinery@gmail.com. Provide the machine model and serial number, fault symptoms, when the issue started, and actions already taken. Photos, alarm records, or video can be shared after the contact channel is confirmed.
Response and on-site attendance are confirmed by project location, issue condition, and service terms. Warranty period and scope follow the specific machine, contract, and after-sales terms. This page does not promise a unified repair time or cost.
What should be done if article wall thickness is uneven?
Collect the machine model, article drawings, material grade, where and when the abnormality appears, and any available measurement records so the technical team can analyze with equipment and process data. Cause cannot be determined from symptoms alone.
Adjustments involving the wall-thickness program, mold, or machine must follow the corresponding manuals and technical guidance. This page does not publish unified adjustment values or repair steps.
What should be done if black spots appear on the article surface?
Record when the abnormality appears, how the article looks, resin and colorant information, recent material changes or cleaning, and provide sample photos that can be checked. The technical team will confirm investigation directions against the specific machine and production records.
This page does not diagnose root cause from black spots alone, and it does not give disassembly instructions for the die head, screw, or electrical system. Handling follows the corresponding manuals and after-sales guidance.
What should be done if the machine does not extrude material?
Record the machine model and serial number, alarm information, conditions before the abnormality, and actions already taken, then contact after-sales. Do not decide which temperature, pressure, or control setting to change from a general web page.
This page does not provide forced start, teardown, or setpoint-change steps. Disposition follows the corresponding machine operating manual and on-site technical guidance.
What should be done in an emergency?
Personnel safety comes first. Follow the emergency procedure for the corresponding machine and the site emergency plan, and contact the on-site responsible person. If anyone is injured or another immediate danger exists, seek on-site emergency help promptly.
When it is safe to do so, contact Waley at +86 138-2969-2592. This page cannot replace site emergency procedures and does not publish unified power-off, pressure-relief, teardown, or restart steps. Follow-up work must be confirmed by qualified and authorized personnel according to the machine requirements.
Maintenance
How often should maintenance be performed?
Maintenance intervals are confirmed per machine model, component, operating conditions, and the corresponding maintenance manual. Intervals from one machine must not be applied directly to another. Check the machine serial number, manual version, and existing maintenance records before setting the plan.
This page does not publish a general maintenance calendar, oil grade, lubrication quantity, or replacement hours. Maintenance services and fees follow the contract and service terms.
How often should the screw be replaced?
Screw life is confirmed per machine model, screw configuration, processed materials, and use/maintenance conditions. A unified public figure or replacement year count is not published. Whether to replace depends on the specific component, inspection records, and confirmed judgment criteria.
Provide machine and screw data, processed materials, and operating/maintenance records to the technical team. Do not decide replacement from a unified wear threshold published on a web page.
How should the die head be maintained?
Die-head maintenance should first confirm the model, configuration, processed materials, and maintenance-manual version. Qualified personnel must follow the confirmed maintenance requirements. Cleaning materials, tools, temperature conditions, and assembly requirements must not be copied across models.
This page does not publish general teardown steps, clearances, temperatures, or fastening parameters. For maintenance needs, provide die-head and machine information and confirm the approach with after-sales.
