LIHE Precision at a glance: PET preform molds, blow molds, closure molds and hot runners from one supplier
LIHE Precision (Foshan Lihe Precision Machinery Co.,Ltd.) is a manufacturer of PET preform molds, blow molds, closure and compression molds, hot runner systems and mold components for the beverage and packaging industry, with manufacturing in Foshan, China. This guide is written for first-time buyers: it explains what each product line covers, which key numbers matter when you compare suppliers, which project route fits your situation and how a mold project with LIHE starts.
What LIHE makes: PET preform molds, closure molds, blow molds and hot runners
LIHE's range covers the tooling that sits on the main machines of a PET packaging line. Each product family has its own category page under Products; the summary below shows the scope of each one so you can go straight to the right page.
- PET preform molds: 32 to 160 cavities, neck finishes such as PCO 1881, PCO 1810, 1716, 3025, 2925, 38mm and wide-mouth sizes up to 90mm, for HUSKY, NETSTAL, SIPA, KATA and other injection molding machines.
- Closure injection molds: 12 to 72 cavities for one-piece and two-piece caps, tamper-evident bands and EU tethered caps in 26mm, 28mm, 2925, 3025 and 38mm.
- Compression molds: tooling for SACMI CCM closure lines, including replacement tooling made from your existing parts.
- Blow molds: two-step molds for SIDEL, KRONES, SIG/KHS, TECH-LONG and NEWAMSTAR, and one-step molds for SIPA, ASB and AOKI, in cold fill, hot fill and aseptic versions.
- Hot runner systems: valve gate systems for up to 144 preform cavities or 96 closure cavities, plus replacement nozzle tips, valve pins, heaters, seals and refurbishment of existing hot runners.
- Accessories and mold bases: blowing pins, stretch rods, clamping bases, mold shells, conversion parts such as star wheels, guides and neck grippers, and precision mold bases for preform molds up to 160 cavities.
Key numbers for PET mold buyers: cavitation, lead time and quality
The figures below are the ones buyers most often ask for in a first conversation. They are LIHE's published values; the figures for a specific project are confirmed in its quotation.
| Item | LIHE figure | Why it matters to a buyer |
|---|---|---|
| Maximum preform mold cavitation | 160 cavities | Higher cavitation raises output per machine cycle |
| Preform mold cavities produced | Over 12,000 per year | Shows production volume and experience with repeat cavities |
| Pilot mold lead time | 20 days | Lets you test a new preform or bottle design quickly |
| Standard PET mold lead time | 8 weeks | Basis for planning a new line or product launch |
| Replacement parts and cap mold parts | 4 weeks | Limits downtime when worn parts must be replaced |
| Process capability | CPK ≥ 1.33 | Critical dimensions stay within tolerance with margin |
| Operational defect rate | As low as 0.0064% | Fewer rejected preforms and less scrap |
| Mold durability | Up to 8 million shots | Built for Husky, SACMI and Netstal platforms |
| Production facility | 15,000 sqm | Design, machining, assembly and inspection on one site |
Where each mold sits in a PET bottle line
A PET bottle line usually needs three kinds of tooling. Knowing which machine each mold fits makes the product pages easier to navigate and helps you describe your project in the first email.
- Preform injection: a preform mold, fed by a hot runner, forms the test-tube-shaped preform with its finished neck thread on an injection molding machine.
- Closure production: caps are made either by injection molding in a multi-cavity closure mold or by compression molding on a rotary line such as SACMI CCM.
- Bottle forming: the reheated preform is stretched and blown into its final shape inside a blow mold, either on a separate stretch blow molding machine (two-step) or on a combined one-step machine.
- Line conversion: when the bottle, neck finish or machine changes, conversion parts such as star wheels, guides and neck grippers adapt the rest of the line.
New mold, replacement parts or retrofit: choosing a project route
Not every project needs a new mold. LIHE supplies several kinds of work, and the right one depends on the condition of your existing tooling and on what you want to change.
- New mold: for a new preform, bottle or closure design, or for a new machine. Standard PET molds take 8 weeks; pilot molds take 20 days.
- Replacement parts and tooling conversion: parts made from your existing Husky, SACMI or Otto parts. Conversion parts are 100% interchangeable for Husky, SACMI, SIPA, NETSTAL, MHT, OTTO, ASB, Krupps and Corvaglia systems. Replacement parts take 4 weeks.
- Retrofit and overhaul: a complete mold overhaul or performance upgrade that restores an aging mold to OEM-level efficiency, including neck finish conversions and lightweighting.
- Hot runner service: replacement nozzle tips, valve pins, heaters and seals, or refurbishment of an existing hot runner.
How to start a PET mold project with LIHE
- Step 1: Send your requirements to sales@lihe-preform.com or by WhatsApp to +886 938 198 675: product drawing or sample, neck finish, preform or bottle weight, cavitation and machine model.

- Step 4: After design approval, components are machined, assembled and measured in the in-house Zeiss CMM lab; validation and inspection reports are supplied on request.
- Step 5: LIHE's technical team supports mold installation and machine start-up, followed by preventive maintenance, remote troubleshooting and spare parts supply.
What to prepare before you request a quote
- Preform or bottle drawing, or a physical sample if no drawing exists.
- Neck finish standard, for example PCO 1881, 29/25 or 38mm.
- Target preform weight in grams and resin type, including any planned rPET share.
- Machine make and model, and whether the hot runner is new or existing.
- Required cavitation and target annual output.
- For blow molds: filling type (cold fill, hot fill or aseptic), bottle volume and blow molding machine model.
Lightweight preform and rPET projects
Many enquiries are about reducing resin use or changing material rather than buying a new mold. LIHE's published results for this kind of work are listed below.
- Preform weight reduced by 1g to 2g through neck or wall-thickness optimization.
- Retrofitting an existing mold for lightweighting costs 25%–40% of the price of a new mold, with a short payback period.
- Optimized cooling can reduce neck cooling time by up to 0.5 seconds.
- Custom work includes rPET material trials, special neck finishes such as PCO 1881 and 29/25, and production line conversions.
Frequently asked questions

- Which countries does LIHE supply?
- LIHE has customers in more than 50 countries across Asia, Europe, the Americas, Africa and the Middle East.
- What guarantee does LIHE offer?
- The published guarantee is a 3-year leakage-proof guarantee on LIHE's Husky Ultra-type hot runner systems. Other commercial terms are set in each quotation.
- Does LIHE publish mold prices?
