What is the production flow in Rapid Scaffold, from material to final products?
Drawings are the first step for producing, and also the most important step.
They include the follows:
a. Those offered directly by customers;
b. Those made according to samples, description or other special requirements, etc.
c. All needed to be changed to drawings fitting producing.
2. Order placed
This step includes product technical standards confirming, preparation before production.
All technical standards should be down to each procedure.
a. Production plan making: raw material & accessory purchasing, working plan, surface treatment, etc.
b. ERP system flow: purchasing application, BOM, workshop production checklists, construction orders, work instructions, and other series of necessary procedures;
c. Molds, tooling and inspection tools preparation
Inspection on raw materials & accessories
Raw materials and accessories are checked according to customers’ requirements.
Inspection on raw material (tubes and plates) includes the follows:
a. Outer diameter
b .Wall thickness
d. Mechanical properties of tensile, yield, elongation
e. Chemical composition (C, P, S, Mn, etc.)
f. Each batch number and mill certificate is recorded and kept for traceability.
At the same time, we own experimental equipments in our research center to check the performance of the corresponding grade. For some special tests, it will be inspected by a third party and a report will be issued.
3. Production flow
Production flow includes: Front workshop (Cutting & punching), Welding workshop, Finishing workshop (Assembling & packing)
3.1 Front Workshop
Also named cutting & punching workshop.
Punching includes: punching, blanking, forming, trimming, lettering, etc.
Cutting includes: pipe cutting to various dimensions, etc.
Machines in the front workshop include: punching machine, cutting, drilling, pipe bending, shearing, bending machines and other equipments.
The various molds required for production are kept in the front workshop, whose price and finishing line are different.
3.2 Molds making
Our molds are mainly punched with plates, punching and chamfering of pipes, etc.
63T punch presses are our regularly used, while large tonnage punches for some thicker plates or complex shapes.
Development cycle: about 10 days for some simple molds, while 30-60 days for large or complex ones.
3.3 Welding workshop
Welding is the key part of production, and it is also the part most likely to go wrong. The quality of welding directly affects the size and shape of products.
We strictly follow the operating specifications in welding process (PWPS PQR WPS), and use welding tooling and fixtures to ensure the finished products meet the drawing requirements.
3.4 Finishing Workshop
Products after surface treated (mainly galvanized and power-coated) are allowed to enter into the finishing workshop after inspection.
Works in the finishing workshop include the follows:
a. Deburring and zinc supplementation;
b. Assembling of part of products (such as wedge plugs, rivets riveting, spigots to standards, diagonal brace head assembly, etc.)
c. Labeling and locking, etc.
Each product must be processed through the finishing workshop before packing.
