Blow mold on extrusion blow molding machine for plastic bottle containers
For over 20 years, Super Jinjun has been designing, manufacturing, and repairing blow molds for all types of blow mold technologies. We started modestly with a handful of employees who wanted to apply their blow mold industry knowledge to the process of making better tooling.at the begining, super jinjun make blow molds on our extrusion blow molding machine only, but time by time, slowly, now it becomes our another normal contribution for our clients, they buy our blow molds on the machine they bought from us, they also buy our blow molds on the machine from others.
Today Super Jinjun for many of world’s top blow molders. Our team of engineers, programmers, machinists, and tool makers are highly experienced in every phase of building the tooling necessary to produce high quality blow molded parts.

In our 120,000 sq. ft facility, we produce extrusion blow molding machine, we also produce has blow molds from 1.5 lbs. to 30 lbs. with part size capabilities ranging from 18 grams to 40 pounds and part dimensions as large as 36” by 66”. We have double station shuttle machines with continuous extrusion capabilities as well as an expertise in numerous materials including HDPE, PP, PC, and PETG. As a complement to our blow molding capabilities, we also offer blow mold repairing services.
Super jinjun uses state-of-the-art equipment and technology to produce complete products from concept to sale with unparalleled quality, accuracy and repeatability. As a blow molding machine manufacturing company, we offer custom extrusion blow molding machine expertise, building on the strength of our people, and their dedication to service and quality, our blow molding machine facility encompasses 120,000 sq. ft. including specific areas dedicated to manufacturing, assembly, warehousing, and shipping. We have the experience and expertise to handle unique and demanding projects, and offer a seamless
turnkey solution for blow molding production. Our mold and machine shop capabilities provide customers with a seamless and efficient process from concept to production capability.
Super Jinjun stays ahead of the curve in order to bring new technologies to the markets that we serve and those that we seek to serve. We work closely with customers and technical partners to find the best technologies for goals and challenges facing our dynamic market place.
Extrusion Blow Molding is the simplest type of blow molding. A hot tube of plastic material, called a parison, is dropped from an extruder and captured in a water cooled mold. Once the molds are closed, air is injected through the top or the neck of the container; just as if one were blowing up a balloon. When the hot plastic material is blown up and touches the walls of the mold the material “freezes” and the container now maintains its rigid shape.
For colored bottles, colorants are often fed into the extruder at a controlled rate and mixed with the resin as they are being melted. If barrier and adhesive layers are required, they are fed separately and combined in a co-extrusion head.
Harpic bottle is widely used on packing of toilet cleaner. as harpic bottle got an angleed neck top, it is not easy produced on normal blow molding machine. it can be produced only on an extrusion blow molding machine and there is an angled blow pin on the EBM machine .for this reason, the blow mold for harpic bottle, it is special designed with angled blowing stairs. as the below picture shows:
This is blowm mold for 200L top open single L ring drum. as the drum is so big, the weight for the mold is up to 1500 kilogram(1.5 tons). also due to it’s size, it is necessary 40 tons mold clamping force. as the picture shows. we add mold clamping Auxiliary devives on this top open single L ring drum blow mold, it provides about 20 T mold clamping force.
During Sterile Blow Moulding, the blow mold is also with special technology. we talk about sterile blow molding, there are these advantages compares with non sterile blow molding:
- The bottle is already sterile at the time it is molded;
- There is no need to use chemical agents that may alter the flavor and organoleptic properties of the content;
- The domo, that is, the part above the neck of the bottle that is sealed, provides a high resistance of the container, which will be useful in case of storage in silos.
Extrusion blow mold with auto-deflash – what it is, why it matters, and how it works
- Definition in one line
An auto-deflash extrusion blow mold is a mold package (or entire molding station) that automatically trims the neck flash, tail flash and side moil while the bottle is still in the tooling, so the parts come out of the machine ready-to-pack without secondary hand trimming.
- Hardware components
| Zone | What it does | Typical design |
| Neck (top) deflash | Removes the dome or ring flash | Pneumatic rotary cutter or direct-push blade integrated in the neck cavity |
| Tail (bottom) deflash | Cuts the pinch-off tail flush with the base | Scissor-type blade driven by a short-stroke cylinder mounted on the back-plate |
| Side moil (if any) | Trims side handles or view-strip moils | Cam-follower knives that move as the mold opens |
| Part eject & take-out | Transfers finished bottle to conveyor | Servo gripper arm synchronized with clamp motion |
- Cycle sequence (8–10 s for 500 ml HDPE bottle)
- Mold opens → blades simultaneously cut neck & tail flash.
- Gripper arm grabs finished bottle and places it on the out-feed conveyor.
- Re-grind blower sucks the flash directly into a beside-the-press granularor for closed-loop recycling.
- Mold closes → next parison is extruded.
No operator intervention = zero labor per cavity, consistent 0.1 mm trim accuracy, and no downstream trimming station.
- Commercial machine examples
- CMP Auto-Deflashing Series – 250 ml to 5 L containers, flash removed in-mold
- Jonh Huah JS-550E – accumulator head for TPE bellows; auto-deflash built-in to meet CPK ≥ 1.67
- AMT Triple-head Auto-deflash – three bottles per cycle, neck + tail flash cut automatically
- DMKD-QK100 – 700 mm dry-cycle double-station with optional auto-deflash package
- Benefits vs. manual trimming
| Metric | Manual | Auto-deflash |
| Labor / cavity | 1 person | 0 person |
| Cycle-time penalty | 0 s (parallel) | 0.2–0.4 s (integrated) |
| Reject rate (trim defects) | 1–2 % | <0.3 % |
| Footprint | Extra trim table | None |
| OPEX (1 000 bph) | ≈ $18 000 / year | ≈ $1 200 / year (blade spares) |
- Typical applications
- Pharma – eye-drop, syrup, tablet bottles (no hand contact)
- Food & beverage – edible-oil, sauce, milk bottles
- Cosmetics – shampoo, lotion, cream jars
- Chemicals – pesticide, lubricant, household cleaner containers
Bottom line
An extrusion blow mold with auto-deflash turns the traditional two-step process (blow + trim) into a single-step, fully automated operation, delivering finished bottles straight from the clamp while cutting labor, space and contamination risk.
