LIANXIN Injection Blow Molds: With the Machine or Separate?

LIANXIN manufactures three\-station one\-step injection blow hollow molding machines and injection stretch blow molding equipment, and its product range includes matching molds and auxiliary equipment\. The delivery scope for a project is governed by the technical agreement\.

So the mold supply question is not settled by the machine series alone: for a specific order, confirm whether the injection blow mold is included in the machine shipment or treated as a separate scope item\. Changeover time also has to be tied to the exact bottle, mold and machine; no single series\-wide figure should be assumed\.

Molds, Machine Scope, and Changeover: What to Confirm

LIANXIN, based in Zhangjiagang, was founded in 2003 and manufactures three\-station one\-step injection blow hollow molding machines and injection stretch blow molding equipment\. Its listed product families are the IBM\-H electro\-hydraulic hybrid servo series \(IBM\-30H, 50H, 80H, 135H\), the IBM\-E all\-electric servo series \(IBM\-30E, 50E, 80E, 135E\), the IBBM\-50E all\-electric horizontal four\-station injection blow machine, and the BPET\-70V4 and BPET\-125V4 one\-step four\-station injection stretch blow machines\. Matching molds and auxiliary equipment are also listed in the product range\. The catalog materials cover HDPE, LDPE, PE, PP, PS, EVA, PET, PETG, PETE, high\-clarity PP/PCTG, SAN, PC, PMMA and BPA\-free TRITAN, with packaging uses in pharmaceuticals, food and dairy, cosmetics, personal care, household products, lubricants and specialty chemicals\.

Those product\-family descriptions are useful for shortlisting a machine type, but they are not a packing list\. LIANXIN states that specific capabilities and delivery scope are subject to the project technical agreement\. For the mold question, the order documents should therefore state whether the injection blow mold is part of the machine supply, a separately packed item, or a separate scope line with its own price and delivery milestone\. Ask for that statement in writing for the exact model and bottle, rather than inferring it from the phrase “matching molds\.”

A practical scope table should separate the machine, each mold set, and the auxiliary equipment\. For every mold, record the bottle drawing or sample, resin, cavity count, mold materials and spare parts, and whether the first production mold is the same one used for the factory acceptance run\. Also record what is mounted on the machine at shipment, what travels separately, and who is responsible for installation and first\-article approval\. These are project\-level technical and commercial choices; they are not pre\-set by the machine series name\.

Changeover time needs the same discipline\. A useful quotation defines the start and end points: for example, from the last good bottle of the old shape to the first good bottle of the new shape, including mold change, machine settings, temperature stabilization, start\-up and quality approval\. A mold\-change\-only time is shorter and should be labelled as such\. Ask for the procedure, the tools required, the number of operators, the checks before restart, and the assumed scrap or trial quantity\. Without those assumptions, one supplier’s number cannot be compared reliably with another’s\.

The quoted time should also identify the machine model and mold set\. LIANXIN’s range spans hydraulic hybrid and all\-electric injection blow machines, a horizontal four\-station injection blow machine, and one\-step four\-station injection stretch blow machines\. A bottle that runs on one model with a particular cavity layout may need a different mold set and a different change routine on another\. Bottle weight, wall thickness, neck finish, resin and the auxiliary equipment all belong in the same discussion\. Ask for the estimate against the actual bottle drawing and resin, not against a generic bottle size\.

Material choice affects the mold and process discussion\. The LIANXIN catalog lists HDPE, LDPE, PE, PP, PS, EVA, PET, PETG, PETE, high\-clarity PP/PCTG, SAN, PC, PMMA and BPA\-free TRITAN, with applications across pharmaceutical, food and dairy, cosmetic, personal\-care, household, lubricant and specialty\-chemical packaging\. When requesting a mold and changeover quote, give the actual resin and any appearance or regulatory requirements for the bottle\. That lets LIANXIN quote the mold construction, surface finish, cooling and change parts for the real application rather than for a family of materials\.

Before placing an order, ask for a short written package: a scope table showing machine, molds and auxiliary equipment; a mold specification per bottle; a changeover procedure with a time definition; a spare\-parts list; and a training or commissioning plan\. If the bottle shape is not final, supply drawings or samples first and ask for the mold and changeover estimate to be reissued against the final design\. This keeps the mold\-supply answer and the changeover answer on the same technical basis\.

Conclusion

LIANXIN injection blow molds are within the company’s product range, but the machine shipment and the mold shipment are not defined by the series name; the project technical agreement sets the delivery scope\. Confirm the mold as a line item, with its bottle, resin, cavity layout and packing split\. For a different bottle shape, request a bottle\-specific changeover estimate with a clear start point, end point and assumptions\. If the final bottle drawing is not ready, settle the mold scope first and ask for the changeover time once the design is fixed\.

Frequently Asked Questions

1. Are LIANXIN injection blow molds supplied with the machine or separately?

LIANXIN lists matching molds and auxiliary equipment in its product range, and the delivery scope is set by the project technical agreement\. Check the agreement and order line items to see whether the mold is included in the machine supply or treated as a separate shipment or scope item; the series name alone does not settle the packing split\.
