Can I download catalogs and drawings from this page?

Not yet. Download resources will be available later; until then, catalogs and technical specifications are sent by the sales team on request.

Do you supply an inspection report with every mold?

Validation and inspection reports from the in-house Zeiss CMM lab are supplied on request. Ask for them in the enquiry or order so the scope of the report is agreed in advance.

Which 3D format should I send for a preform or bottle?

STEP is the most widely used neutral format. Add a dimensioned PDF drawing with tolerances, because the 3D model alone does not show what will be checked.

Can you make parts if I only have the old part and no drawing?

Yes. Replacement and conversion parts are made from customers' existing parts or drawings, so a sample part can serve as the reference when no drawing is available. Replacement parts have a published lead time of 4 weeks.

Will I receive the machine interface data before the mold arrives?

Interface data should be agreed during design, before production. If you are unsure about your machine's interface, the technical team can carry out an on-site machine interface audit.

Technical documents for PET preform molds, blow molds and hot runners: what buyers need and how to request them

Updated October 13, 2026Author: LIHE Precision Engineering Team

A technical document package is the set of drawings, specifications, inspection reports and machine interface data that a buyer uses to approve, install, maintain and re-order a mold. 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. Catalogs and technical documents are currently provided by the sales team on request; this guide explains which documents to ask for at each project stage and which file formats are common.

Which technical documents PET mold buyers typically need

Different people in a bottling or preform plant need different documents. Purchasing compares offers, the process engineer checks the product, the maintenance team needs part references, and quality needs measured data. Asking for the right document at the right time avoids delays at approval and at start-up.

Product catalog and capability overview: product range, cavitation range, supported machines and neck finishes, for supplier evaluation.
Product drawings: preform, closure or bottle drawings with dimensions and tolerances, for product approval.
Mold layout or general arrangement drawing: overall mold dimensions, cavitation, connection points, for checking machine fit.
Part drawings and spare parts lists: core, cavity, neck ring, gate insert or blow mold parts, for maintenance and re-ordering.
Inspection and validation reports: measured dimensions from the CMM, for incoming quality control.
Machine interface data: mounting, cooling, electrical and ejection connections, for installation.

Part drawings and spare parts list	Maintenance, re-ordering of wear parts	Delivery and service life	PDF, STEP, spreadsheet list
CMM inspection report	Incoming inspection, process capability	Before shipment	PDF report
Machine interface data	Installation and start-up	Design and installation	PDF drawing, checklist

Drawings and 3D files: STEP, IGES, DWG, DXF and PDF

Mold and product geometry is usually exchanged in neutral formats so that both sides can open it regardless of the CAD system they use. Tell sales which format your team works with when you request or send drawings.

STEP (ISO 10303-21) is the most common neutral format for 3D solid models of preforms, bottles, closures and mold parts.
IGES is an older neutral format that is still used for surfaces and for exchange with older CAD systems.
DWG and DXF are 2D drawing formats often used for layouts, plate drawings and machine interface drawings.
PDF is used for dimensioned drawings, reports and approvals, because it shows tolerances and notes exactly as issued.
For approval, a 3D model alone is not enough: dimensioned 2D drawings show the tolerances that are checked during inspection.

Preform, closure and bottle specifications

A specification sheet records the values that the mold must deliver. It is the reference for design approval and later for checking samples. Typical contents depend on the product.

Preforms: weight in g, total length, neck finish (for example PCO 1881, PCO 1810, 2925 or 38mm), wall thickness profile and resin (PET or a share of rPET).
Closures: cap type (one-piece, two-piece, tamper-evident, EU tethered), neck size such as 26mm or 28mm, cap weight and material.
Bottles: volume in ml, fill type (cold fill, hot fill at about 85 to 95°C, or aseptic), base design, label panel and the matching preform.
Lightweighting projects: the current and target weight; LIHE lightweighting proposals reduce preform weight by 1g to 2g through neck or wall-thickness optimization.
Every change to a specification should be recorded with a revision letter and date, so that drawings, molds and samples can be traced.

Inspection and validation reports from the Zeiss CMM lab

LIHE measures mold components in its in-house Zeiss CMM lab, and validation and inspection reports are supplied on request. A coordinate-measuring machine (CMM) measures points on a part and compares them with the nominal geometry, so the report shows actual values against tolerances.

Ask for the report in your enquiry or order, and list the dimensions or features you want included, for example cavity, core and neck ring dimensions.
For high-cavitation molds, ask how many cavities or parts are measured, because a 72-cavity or 96-cavity mold has many identical positions.
Process capability is often stated as Cpk; LIHE tooling consistently achieves CPK ≥ 1.33.
Keep the report with the mold records: it is the baseline for later wear checks and refurbishment.

Machine interface data for mold installation

Machine interface data describe how the mold connects to the injection or blowing machine. Errors here are found only at installation, so this data should be agreed during design. LIHE's technical team also carries out on-site machine interface audits.

Mounting: platen dimensions, tie-bar clearance, locating ring and clamping pattern.
Cooling: water connection positions, thread types and circuit layout.
Hot runner: heater zones, thermocouple type and connector layout, valve gate actuation.
Ejection and take-out: stroke and interface to the robot or take-out plate.
Blow molds: mold carrier type, shell or clamping base interface and base mold connection.

How to request technical documents from LIHE sales

Step 1: Email sales@lihe-preform.com or use the contact form, and state the product type and the machine brand and model.
Step 2: List the documents you need, using the table above, and the file format your team prefers (for example PDF and STEP).
Step 3: If the request concerns an existing mold or part, add the mold number, part number or photos so the correct drawing revision is used.
Step 4: Sales confirms which documents can be supplied at the current stage; project-specific drawings and reports are prepared for your project, not taken from a general download library.
Step 5: Review the received drawings, mark any changes and return them with a revision note before design approval.
