Industrial Applications

Plastic jar lids manufactured using our moulding services are suitable for:

Manufacturing Process

Our Plastic Jar Lid Mould and Moulding Service follows a systematic manufacturing process to achieve reliable mould performance and consistent finished products.

Product Design & Development

Customer drawings, 3D models, physical samples, jar neck dimensions, lid diameter, thread profile, sealing requirements, closure mechanism, dispensing features, and branding requirements are reviewed before mould development.

Engineering & Mould Flow Analysis

The lid design is evaluated for wall thickness, draft angle, shrinkage, gate position, cooling requirements, parting line, ejection system, thread geometry, sealing features, and mould filling.

Mould Design

The plastic jar lid mould is designed using CAD/CAM software according to the required product geometry and injection moulding machine specifications.

CNC & EDM Machining

Mould components are manufactured using CNC machining, EDM, Wire Cut EDM, drilling, and grinding processes for accurate dimensions and high-quality mould surfaces.

Mould Assembly

Individual mould components are assembled and checked for cavity and core alignment, cooling channels, ejector operation, guide systems, inserts, unscrewing or thread-forming mechanisms, and proper mould closing.

Mould Trial & Sampling

Trial jar lids are produced for dimensional accuracy, thread fitment, sealing performance, closure operation, opening torque, jar compatibility, surface quality, and visual verification.

Injection Moulding Production

Selected plastic material is heated and melted inside the injection moulding machine and injected into the mould cavity under controlled pressure and temperature.

Cooling & Ejection

The moulded jar lids are cooled and carefully ejected to maintain dimensional stability and prevent deformation.

Finishing & Assembly

Flash and excess plastic are removed. Where required, liners, seals, inserts, dispensing components, tamper-evident bands, or other compatible components are assembled.

Branding

Logos, product codes, embossed patterns, printing areas, and other customized branding features can be incorporated according to customer requirements.

Quality Inspection

Finished jar lids are inspected for dimensions, thread fitment, sealing, closure performance, surface quality, weight, and overall product consistency.

Raw Materials

Material selection should be based on the required strength, flexibility, chemical compatibility, temperature performance, sealing requirements, transparency, durability, and intended application. For direct food or pharmaceutical contact, the selected material should meet the applicable requirements for that application.

Mould Material

The final mould steel is selected according to production quantity, product design, expected mould life, surface finish, plastic material, and customer requirements.

Quality Control

We maintain strict quality control throughout mould manufacturing and plastic jar lid production.

Raw Material Inspection

Plastic materials are checked for grade, quality, color, and suitability before production.

Mould Dimension Inspection

Critical mould dimensions, cavity alignment, cooling channels, ejector system, guide components, inserts, thread-forming components, and tolerances are inspected before mould trials.

First Sample Inspection

Initial jar lid samples are checked against approved drawings, samples, or specifications.

Dimensional Inspection

Lid diameter, height, wall thickness, thread dimensions, sealing features, inner plug dimensions, and other critical measurements are verified.

Thread Fitment Inspection

The lid is checked against the intended jar neck to verify proper threading, engagement, opening, and closing.

Sealing Inspection

Where applicable, sealing rings, liners, inner plugs, and sealing surfaces are checked for proper fitment and closure performance.

Closure Inspection

Screw, snap-fit, push-fit, flip-top, or other closure mechanisms are inspected for proper operation.

Tamper-Evident Inspection

Where applicable, tamper-evident bands and breakable features are checked for correct dimensions and functionality.

Weight Inspection

Finished jar lids are checked for consistent product weight according to the approved specification.

Visual Inspection

Products are inspected for flash, sink marks, warpage, short shots, scratches, bubbles, flow marks, black spots, and other surface defects.

Surface Finish Inspection

Surface texture, gloss, matte finish, embossing, logos, labels, and other finishing requirements are inspected according to approved specifications.

Packaging Inspection

Finished jar lids are securely packed to minimize scratches, deformation, contamination, and damage during handling, storage, and transportation.
