Factory

A plant you can walk through on paper.

Moulding, assembly, inspection and packing under one roof. The sections below show what happens at each station and which documents travel with the order.

From resin to carton

Four stations, in this order, for every order we run.

Moulding station at the straw cup factory

01

Moulding

Bodies, lids and straws moulded in house, with first-article checks on each run.

Assembly station at the straw cup factory

02

Assembly

Gaskets, straws and handles fitted at dedicated stations, not mixed into packing.

Inspection station at the straw cup factory

03

Inspection

Leak, fit and appearance checks on sampled units from every batch.

Packing station at the straw cup factory

04

Packing

Cartons marked to your instruction, photographed before the container is closed.

Quality control

Checks at three points, not one.

Leak, fit and appearance problems are cheapest to catch before packing, so inspection is scheduled into the run rather than at the end.

  1. Incoming material

    Per batch

    Resin, silicone and steel checked against the declared grade before release to the line.

  2. In-process

    Per batch

    Hourly sampling on dimensional fit, lid seal and straw retention.

  3. Final batch

    Per batch

    AQL-based appearance and function inspection, with photos filed against the order.

Who answers

Our Sales Team

The sales desk sits beside the tooling and QC teams, so questions on moulds, sampling slots and monthly capacity come back in one thread rather than three.

Not sure who to ask? One message reaches the whole desk.
