Maintenance & replenishment
PET blow molding shock absorbers for maintenance
Prepare shock absorber replenishment for planned maintenance on PET bottle blowing machines. Start with the fitted part and its machine position; EKD can review the information before you request a confirmed model and quotation.
Request maintenance sparesIdentify the stretch-rod or mould mechanism
PET stretch blow-moulding machines can use different shock absorber designs at the stretch-rod and mould mechanisms. Record the exact position and equipment generation from the machine documentation. Parts fitted at different positions should be identified separately.
Check the installed dimensions and operating duty
Provide the body marking, mounting thread, installed length, usable stroke and contact arrangement where available. For a technical review, include impact frequency, contact speed, moving load and time available for the absorber to return. EKD application material covers dedicated absorbers for repeated stops in PET machinery; performance must be confirmed for the selected model.
Prepare the next maintenance order
Separate the quantity required for the planned maintenance job from additional store stock. Tell us the delivery country and required date. Confirm the model and delivery schedule before scheduling installation; an enquiry does not reserve inventory.
From identification to repeat orders
1. Identify the part
Send the existing code and machine details. If the marking is unclear, send a close-up and an installation photo by email or WhatsApp.
2. Confirm the specification
We review dimensions, stroke, mounting and operating duty before proposing a model. Quote and delivery availability are confirmed for the requested quantity and destination.
3. Keep a replenishment record
After technical confirmation, keep the approved model, machine position and order reference together. Include that reference with your next maintenance order.
Maintenance purchasing questions
How often should a shock absorber be changed?
Use the machine maintenance instructions and the exact shock absorber specification. Cycle count, load, return time and environment affect the inspection and replacement plan; one calendar interval does not apply to every machine.
Can I order from a machine brand or a matching thread alone?
Please also provide the part code and installation position. Matching threads do not establish stroke, damping or duty suitability. Any proposed fit must be checked for the particular machine and part.
Can service companies and spare-parts distributors enquire?
Yes. Send the machine types you support and the shock absorber codes on your maintenance parts list. Include quantities and delivery dates for each item so they can be reviewed separately.
