Reheat Stretch Blow Molding Machinery

• Made in Taiwan
• High quality machines and molds

• Excellent outputs and quality at lower cost

1 Cavity Fully Automatic Shuttle Model TS1000

• Excellent Price
• Excellent Performance

• 1 to 6 cavities
• Most widely used machine type for small to medium sized applications
• Outputs from 1,000 to 8,400 b/h with all - electric model
• Neck sizes from 30 to 200 mm
• Volumes from 50 ml to 5 gallons
• Heat set, thread orientation, and preferential heating available on some models

• Shuttle means that the movement through the ovens is 'go - and stop'
• + Low capital investment
• + Easy setup
• Preform heat Iess than continuous motion machines; to compensate Chumpower machines allow the adjustment of blow parameters for individual cavities
• Spacing in ovens is the same as in blow mold - this is not as efficient as more air is heated up and escapes

• CPSB: Chumpower Stretch Blow
• T: Standard
• Number: Number of cavities times 1,000 (except in rotary and LS machines)
• L: Large container
• W: Wide Mouth
• H: Heat - Set
• H: Rotary
• SS: Small Size (0.6 I maximum)

Wide Mouth Containers

• One or two cavity machines available for diameters (mouth) up to 200 mm, standard

• CPSB-1000L / 2000L
• CPSB-1000W / 1000WM / 2000W
• CPSB-2000LHI

Output :
• 800-1600 bph

Cavities :
• 1 – 2

• This linear rnachine is different in several ways:
• In - feed is like a rotary machine with star wheels:
• proven concept with high reliability
• Movement of preforms through the ovens is
• continuous: even heat for all preforms
• Spacing in ovens is fixed depending on model;
• preforms are then spread to blow mold pitch: batter use
• of ovens, energy savings
• Servo motor clamp: fast and reliable

• Compact design
• Space savings
• Easy access
• Easy maintenance

• Compact design
• Space savings
• Easy access
• Easy maintenance

• Modular ovens with easy access
• 50 mm preform spacing for best energy usage
• Preform are always right side up eliminating turn over problems, chain wear etc.
• 2 x 3 ovens layout with turnaround section for equalization of preform temperature

• Chumpower lamp spacing is 17 mm {155mm on request)
• Lamps can be moved
• 6 to 16 lamps per oven
• Each lamp can be turned on or off
• Heat shield is watercooled

• Preform transport and pitch unit are both controlled by servo motors
• Pitch unit grabs preforms, then moves them towards blow clamp and enlarges the pitch to blowing dimension

• Toggle clamp triggered by cam
• Cam controlled by servo motor
• Cam rotates continuously in one direction greatly reducing vibration
• Patented design
• Stretch rod is servo motor controlled
• Each cavity has its own set of blow valves allowing individual control and reducing air consumption
• Blow nozzle seals on transfer ring - no neck deformation
• Bottom insert movement is mechanically coupled to clamp
• Pressure compensation reduces bottle parting line and mold wear

• CP offers a 10 - cavity machine at this time
• There are 4 models:
• CPSBR - 10 - 36: Max. neck 28 mm, oven pitch 38 mm
• CPSBR - 10 - 50: Max neck 43 mm, oven pitch 50 mm
• Both machines have a maximum output of 14,000 b/h
• CPSBH - 10 - 38H; Same as above for heat - set
• CPSBH - 10 - 50H: Same as above for heat - set
• Heat set machine output is 10,000 b/h

• Every preform is exposed to the exact same amount of heat and time between heating end blowing
• Small oven pitch allows efficient heating
• Synchronization is mechanical and, once set, very repeatable
• Low dead - volume of air means lower air consumption
• In - feed end out - feed are both mechanical and not prone to failure.
• Pressure compensation means Iess stress on mold

• In indexing machines pitch of mandrels in the ovens is the same as in blow mold "4"
• Ovens are not loaded optimally
• Large necks possible
• In rotary and LS - 6000 machine pitch is either 38 or 50 mm
• Energy savings due to better oven usage
• Neck size limited by pitch: transfer ring must be 1.5 mm smaller than pitch

• Blow machines need 30 to 40 bar (420 to 580 psi) air pressure
• Compressor is by far the most expensive ancillary equipment for stretch blow molding
• PET All compressors use a Chinese supplier that came out of lngersoll - Rand as the best compromise between low cost and reliability
• These compressors are modular. Single unite of 20 to 40 cfm are stacked together to form larger systems that can easily be expanded
