Top-Fill Hardware and Tray Capping
Compatible POSTLESS® hardware is designed to simplify access during filling and support tray-based handling from oil injection to lid placement.
At Maxcore, we don't just manufacture exceptional vape hardware - we provide end-to-end oil filling services designed to streamline your production and improve operational consistency.
Compatible POSTLESS® hardware is designed to simplify access during filling and support tray-based handling from oil injection to lid placement.
The wide top-fill opening reduces alignment demands during manual or semi-automated filling, making nozzle access easier and supporting a more repeatable vape cart filling workflow when validated operating parameters are used.
The CLACK snap-on lid format allows compatible devices to be handled in trays during filling and capping, reducing individual handling steps. Before production, confirm tray fit, fill settings, cap seating, and equipment compatibility for the selected device.


Maxcore provides product-specific oil filling instructions for compatible hardware, covering preparation, filling sequence, handling, capping, and process checks. Optional on-site guidance can help production teams review equipment setup, operating steps, and common filling issues at their facility.
Final parameters should be validated for the selected device, oil formulation, filling equipment, and production environment. This guidance supports the customer’s process development but does not replace its own quality-control or compliance responsibilities.

Maxcore’s oil filling services connect compatible hardware, product-specific instructions, optional on-site guidance, and automation coordination within one production-support workflow.
Share your device format, oil type and viscosity, target fill volume, batch size, capping method, equipment, and production timeline. Maxcore can help assess cartridge filling & capping solutions for compatible products.
