How to Prepare a Trial Production Run Before Mass Producing Concrete Blocks

Trial production is the bridge between installation and stable mass production. It helps the factory test materials, molds, water dosing, vibration, demoulding, pallet movement, curing, and handling before accepting large customer orders. Skipping this step can turn a new block machine into a daily experiment.

This article explains how to prepare a trial run for a concrete brick machine plant and how to turn trial results into practical production standards for a stable brick making machine line.

Why trial production is needed

A supplier can test the machine before shipment, but the customer's raw materials, climate, power, operators, pallets, and curing conditions are different. Trial production verifies whether the complete block making machine line works in the real factory environment. It also helps train operators before pressure from real orders begins.

The trial should not only prove that blocks can be made. It should define the first stable settings: formula, moisture range, cycle behavior, vibration time, pallet flow, curing method, and quality inspection points.

Prepare materials and equipment

Before trial production, prepare cement, aggregate, water, pallets, molds, tools, forklift, curing area, and quality inspection method. The batching machine, cement silo, and concrete mixer should be checked before the first batch.

Confirm product drawings and mold layout. A hollow block mould, interlocking paver mould, or kerbstone mold will require different trial observations. Operators should know what product quality looks like before the machine starts.

Run small batches

Start with small batches. Produce a few boards, stop, inspect, and adjust. Do not run full speed before the mix and machine behavior are stable. Check whether material fills the mold evenly, whether the fresh products release cleanly, and whether the pallet carries the product without deformation.

When the trial includes pavers, pay close attention to surface texture, color, height, and edge sharpness. When it includes hollow blocks, check web formation and handling strength. When it includes kerbstones, check straightness, product height, and bottom surface.

Inspect and adjust

Adjust only one item at a time. If water, vibration, feeding time, and pressure are all changed together, the team will not know which change solved the problem. Record every adjustment. A trial sheet should include formula, water correction, mold number, cycle observation, product defect, and final accepted setting.

Downstream equipment should also be tested. A stable GMT pallet, an automatic pallet provider, and an offline palletizing system can improve production only when their timing matches the forming machine.

Hawen Machinery support

Hawen Machinery supports trial production by reviewing product type, raw materials, molds, pallets, curing method, and automation level. The SIEMENS S7-200 PLC with touch panel and remote monitoring helps review machine status. The hydraulic station uses Japanese YUKEN valves with an American ALBERT hydraulic pump for precise motion control.

The four-shaft vibration box with external eccentric blocks supports uniform compaction when the mix is correct. Trial production is where these machine advantages meet local materials. A careful trial turns a new line from installed equipment into a factory standard that can be repeated every day.

FAQ

1. How many boards should be made during trial production?
   Enough to confirm material behavior, machine rhythm, demoulding, curing, and handling. The number depends on product type and plant complexity.

2. Should trial products be sold?
   Only if they meet quality requirements. Trial products are mainly for setting process standards.

3. What should be recorded during the trial?
   Record formula, moisture, mold, settings, defects, adjustments, curing condition, and accepted parameters.

4. Can trial production use only one product?
   Start with the main product, then test other important molds before accepting large orders.

5. Why do trial blocks look different from factory test blocks?
   Local materials, water, climate, pallets, curing, and operators may differ from the supplier's test environment.

6. Can Hawen help after trial production?
   Yes. Hawen can review parameters and product feedback to help stabilize mass production.
